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. A correct conversion requires an ICC profile transform from CMYK to sRGB. Convertify applies this automatically using the US Web Coated SWOP v2 profile. If you used a tool that does naive arithmetic conversion, reds will appear orange and blues will appear grey.
- 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?
- Yes, if you know the password. Enter it when prompted and Convertify decrypts locally before rendering. If you do not know the password, use our PDF unlock tool to remove protection first.
- Is there a file size limit? Do you add a watermark?
- No file size limit and no watermark — ever. Convertify is free for all conversions. Files are deleted automatically after you download.
- Does Convertify store my PDF after conversion?
- No. Files are processed in isolated server workers and deleted immediately after your download completes. Nothing is logged, stored, or accessible to third parties.
- What rendering engine does Convertify use?
- Convertify uses libvips 8.17+ with a PDFium backend. PDFium is Google Chrome's PDF renderer — the same engine that renders PDFs in Chrome, Edge, and Android WebView. libvips streams pixels in tiles so even 600 DPI conversions run in constant memory without OOM errors.
- 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.
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.

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 uses PDFium's Skia-based analytical coverage). Fourth, libjpeg-turbo encodes the scanline buffer to JPEG with the quality and chroma subsampling you selected. 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 — explained and solved
PDF supports DeviceCMYK, ICCBased CMYK (US Web Coated SWOP v2, FOGRA39, GRACoL 2006), DeviceN, and Separation color spaces. JPEG supports only RGB. The conversion requires an ICC-profile transform: CMYK source → PCS (L*a*b* or XYZ) → sRGB target, mediated by lcms2 or Skia CMS. Most tools skip this and use naive arithmetic: R = (1−C)×(1−K), G = (1−M)×(1−K), B = (1−Y)×(1−K). This is wrong because real ink dot gain is non-linear, rich blacks (C=40 M=30 Y=30 K=100) ignore chromatic cast, and saturated process blues become muddy violet. Convertify applies a full ICC transform via libvips vips_icc_transform() with a US Web Coated SWOP v2 source profile when no embedded profile is declared. If your reds look orange or your blues look grey after converting a print-design PDF, this is almost certainly the cause — and Convertify handles it correctly.
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 critical second setting 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 catastrophic — red or blue letters bleed across 2×2 luma blocks, producing colored fringing. Convertify forces 4:4:4 chroma subsampling (full chroma resolution) at Q90 for any PDF that contains text elements, and uses 4:2:0 at Q85 only for photo-only pages. The other factor is DCT block artifacts ('mosquito noise') around sharp glyph edges — the structural reason PDF text looks fuzzy as a JPEG and perfectly sharp as a PNG.

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 — no amount of DPI increase will add detail that was never there. Colors look washed out or shifted: the source PDF uses CMYK. Convertify handles this with an ICC transform, but verify by comparing Convertify output to Adobe Acrobat. 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 DPI to 200 for screen use. JPG has no alpha channel — if you need a transparent background, use our PDF to PNG converter. Password-protected PDFs: enter the owner password when prompted; if unknown, use our PDF unlock tool first. Large PDFs timing out: split into 10-page chunks using our PDF splitter, then convert each batch.
