Frequently Asked Questions
- What DPI should I use to convert PDF to JPG?
- 72 DPI for thumbnails and email previews (595×842 px for A4). 150 DPI for office documents and WhatsApp sharing (1240×1754 px). 300 DPI for print-ready output, the minimum for photo labs and magazines (2480×3508 px). 600 DPI for archival, OCR, or large-format print (4960×7016 px). You cannot add detail after the fact, always export at your highest target DPI.
- Why does my converted JPG look blurry?
- Almost always a DPI issue, the default on most tools is 72 DPI, which produces only 595×842 pixels for an A4 page. Re-convert at 300 DPI. If still blurry, the source PDF contains a rasterized scan at low resolution, no DPI increase will help. For text-heavy PDFs, PNG output looks sharper because JPEG DCT creates ringing artifacts around sharp glyph edges.
- Why do my PDF colors look wrong in the JPG?
- The source PDF uses CMYK color space (common in print-design files from InDesign, Illustrator, or Photoshop). JPEG is RGB-only, so the page has to be converted to RGB. Convertify renders the PDF with poppler, which converts CMYK to RGB during rasterization. This is a direct render rather than a managed ICC transform with a named print profile, so if you need exact print color, finish the CMYK work in a prepress editor.
- How do I convert a multi-page PDF, do I get one JPG per page?
- Yes. Convertify converts every page to a separate numbered JPG (page-001.jpg, page-002.jpg, etc.) and bundles them into a single ZIP archive. You can also specify a page range if you only need certain pages.
- Can I convert a password-protected PDF to JPG?
- Convertify converts unlocked PDFs. If your PDF is password-protected, open it in your PDF viewer, remove the password, and save an unlocked copy first, then convert that.
- Is there a file size limit? Do you add a watermark?
- There is no watermark, ever, and Convertify is free for all conversions. Uploads are capped at 20 MB total per batch. Your converted file stays available to download for 6 hours, then it is removed from the server automatically.
- Does Convertify store my PDF after conversion?
- Your converted file stays available to download for 6 hours, then it is removed from the server automatically. Convertify is free and needs no signup to convert.
- What rendering engine does Convertify use?
- Convertify renders PDF pages with libvips using the poppler PDF engine, then encodes each page to JPG. libvips streams pixels in tiles, so even 600 DPI conversions run in low, steady memory instead of loading the whole page at once.
- JPG or PNG, which should I choose for my PDF?
- JPG for photographs, scans, and any page with full-color gradients heading to email, social media, or print. PNG for text-heavy pages, logos, diagrams, and any content needing transparency. PNG is lossless, zero quality degradation and no ringing artifacts around text. For a typical A4 text page at 300 DPI, PNG is often smaller than JPG because DEFLATE compresses flat-color runs more efficiently than DCT.
- How do I convert PDF to JPG on a Mac using Preview?
- Open the PDF in Preview → File → Export → Format: JPEG → Quality: Best → Resolution: 300 DPI. Important: multiple macOS versions (Big Sur, Ventura, Sonoma) have a confirmed bug where the resolution field is ignored and the output is always 72 DPI. If your exported JPG is 595×842 px for an A4 page, you hit this bug. Use Convertify or Automator instead.
- Can I convert only specific pages of a PDF to JPG?
- Yes. When you upload a multi-page PDF, switch from All pages to Choose pages and enter the pages you want, for example 1-5, 8, 12. Convertify converts only those pages to JPG and returns them together as a ZIP. This is the fast way to extract a single page or a page range from a PDF as JPG without converting the whole document.
- How do I save a PDF as JPG or export PDF pages to images?
- Saving a PDF as JPG and exporting PDF pages to images are the same thing here: upload the PDF, pick your DPI, and Convertify converts every page to a JPG image you can download. There is no separate export step or software to install. To turn a single PDF page into a JPG, use Choose pages and enter just that page number.
- What if the output JPG file is too large?
- You can <a href="/compress/jpg">compress the JPG</a> to reduce file size without visible quality loss. Convertify's JPG compressor typically reduces photos by 40 to 60%.
- Can I resize the image during conversion?
- Yes. Use Convertify's <a href="/resize-image">image resizer</a> to set a custom width or crop to exact dimensions.
- Can I resize the image during conversion?
- Yes. Use Convertify's <a href="/resize-image">image resizer</a> to set a custom width or crop to exact dimensions.
Pick your DPI before you click Convert, it actually matters
DPI (dots per inch) controls how many pixels the rasterizer samples per inch of page. A PDF page has no inherent resolution, it is a vector description. Every pixel in your output JPG is created by the renderer.
At 72 DPI you get one pixel per PDF point (the native unit), fine for a thumbnail but unreadable for body text on a HiDPI screen. At 150 DPI text becomes legible; at 300 DPI it matches the minimum standard for offset printing; at 600 DPI you can run OCR or print A2 posters without visible pixelation. The rule: never upscale a low-DPI JPG after conversion, JPEG cannot reconstruct detail that was never sampled.
Set the DPI you need upfront, even if the output file is large.
For lossless rasterization of text-heavy pages, try PDF to PNG. For web-optimized output, try PDF to WebP.

How the rendering pipeline works, what competitors won't tell you
PDF-to-JPG conversion runs through four stages. First, the PDF parser reads the file trailer, locates the cross-reference table, and walks the object graph from /Root → /Pages → /Page, extracting content streams (usually FlateDecode-compressed). Second, a graphics interpreter executes roughly 73 PDF operators against a Graphics State that carries the current transform matrix, clipping path, color spaces, line widths, alpha values, and blend modes.
Text uses Type 1, TrueType, CIDFontType0, or CIDFontType2 glyph outlines, if a font is not embedded in the PDF, the renderer substitutes a system fallback, which is the root cause of every 'fonts look wrong' report. Third, the rasterizer scan-converts paths and glyphs with anti-aliasing (Convertify renders this stage with poppler, which rasterizes through Cairo). Fourth, libjpeg-turbo encodes the scanline buffer to JPEG at quality 85.
Convertify runs this entire pipeline through libvips, which streams pixels in tiles rather than loading the full decoded page into RAM, so a 600 DPI A4 page (139 MB raw) never causes an out-of-memory error.
CMYK PDFs and the color shift problem
PDF supports DeviceCMYK, ICCBased CMYK (US Web Coated SWOP v2, FOGRA39, GRACoL 2006), DeviceN, and Separation color spaces. JPEG supports only RGB, so every CMYK page has to be converted to RGB before it can be saved as a JPG.
Convertify renders PDF pages with poppler, which converts CMYK to RGB while it rasterizes the page. This is a direct render, not a managed color transform: there is no named output ICC profile (such as SWOP or GRACoL) and no custom rendering intent applied on top. For most documents the rendered color is close to what you see in a PDF viewer. If you need exact, print-accurate separations, do the CMYK work in a prepress editor that lets you assign the target profile.
Need pixel-perfect text or a transparent background instead? Try PDF to PNG.
JPEG quality, chroma subsampling, and text sharpness
JPEG quality controls the quantization table scale: Q85 is roughly 50% the size of Q95, and Q100 is 4–6× Q85. But quality alone does not determine text clarity. The second factor is chroma subsampling.
Most encoders default to 4:2:0 below quality 90: the chroma channels are subsampled 2× in both axes, halving their resolution. For photographs this is invisible. For text it is harsh, because red or blue letters bleed across 2×2 luma blocks and produce colored fringing.
Convertify saves JPG at quality 85 with libvips default settings, tuned for photographic pages. For text-heavy pages the sharper choice is PNG: it has no DCT block artifacts or mosquito noise around glyph edges, which is the structural reason PDF text looks crisp as a PNG and slightly soft as a JPG. See PDF to PNG for text and line art.

Troubleshooting blurry output, wrong colors, and other common problems
Blurry or pixelated JPG: you converted at 72 or 96 DPI. Re-run at 300 DPI. If text is still soft, the source PDF contains a rasterized scan at low native resolution, and no amount of DPI increase will add detail that was never there.
Colors look washed out or shifted: the source PDF uses CMYK, which poppler renders to RGB during rasterization. The result is a direct render without a managed ICC profile, so compare against Adobe Acrobat if you need exact print color.
Fonts look different or substituted: the PDF was created without embedding fonts (common in older Word exports). Re-export the source document with 'Embed all fonts' enabled.
File too large: lower quality to 80 and use 150 DPI for screen use. JPG has no alpha channel, so if you need a transparent background use our PDF to PNG converter.
Password-protected PDF: remove the password in your PDF viewer first, then convert the unlocked copy.
Convert PDF to JPG on every device
Windows 10/11: Convertify in Edge or Chrome, no installation. Microsoft Print to PDF creates PDFs but cannot convert them. PowerToys does not include PDF-to-image.
Power users: install poppler-utils via Chocolatey (choco install poppler) then run pdftoppm -r 300 -jpeg input.pdf page. Mac: Preview.app exports JPEG but its resolution field is widely reported to be ignored on Big Sur, Ventura, and Sonoma, always outputting 72 DPI regardless of the setting (Apple Discussions threads 252195525 and 252060872). For 300 DPI use Convertify or Automator: New Quick Action → PDF files → Render PDF Pages as Images (Format JPEG, Resolution 300) → Move Finder Items.
iPhone/iPad: open Safari → Convertify web app → save to Photos. iOS Shortcuts has no direct PDF-page-to-JPEG primitive. Android: open Chrome → Convertify → Downloads.
Samsung My Files cannot convert. Chromebook: no native tool; ChromeOS Crostini users can install poppler-utils in the Linux subsystem.
You do not have to convert the whole document. For a multi-page PDF, choose Choose pages and enter a range like 1-5, 8, 12 to convert only the pages you need, delivered as a ZIP.
JPG vs PNG for PDF pages: which to choose
The right format depends on what is on the page, and we measured both on the same PDF rendered through Convertify. For photographic pages, JPG is dramatically smaller: at 72 to 150 DPI a photo page was 86 to 91% smaller as JPG than as PNG. For text, line art, logos, and diagrams it flips: PNG was 13% smaller at 150 DPI, 26% smaller at 300 DPI, and 37% smaller at 600 DPI than JPG, and it stays razor sharp because it has no JPEG block artifacts on glyph edges. One surprise worth knowing: at very high DPI even photo pages can come out smaller as PNG (at 600 DPI the photo page was about 45% smaller than JPG), because the upscaled image becomes smooth enough for lossless compression to win. The short version: convert PDF pages to JPG for photos, scans, and anything headed to email or social media, and use PNG for text-heavy pages, logos, and screenshots that must stay crisp.
