Frequently Asked Questions
- Will I lose quality converting PNG to JPG?
- JPG uses lossy compression, so there is some quality loss compared to lossless PNG. At high quality settings (80+), the difference is invisible for photographs. For logos, icons, and text, quality loss is more visible — keep these as PNG.
- How much smaller will my JPG be compared to PNG?
- For photographs, typically 70-85% smaller. A 20MB PNG photo becomes a 3-5MB JPG at high quality. For simple graphics and logos, the size reduction is smaller since PNG already compresses these efficiently.
- Does converting PNG to JPG remove transparency?
- Yes. JPG does not support transparency. Any transparent areas in your PNG will be filled with white. Use WebP or keep the PNG if you need transparency.
- What quality setting should I use for PNG to JPG conversion?
- 80% quality is the standard recommendation for web use — excellent visual quality with significant file size reduction. Use 90%+ for professional printing or archival purposes. Use 60-75% if file size is critical and the image is a photograph without fine detail.
- Can I convert multiple PNG files to JPG at once?
- Yes. Convertify supports batch conversion — upload up to 10 PNG files and download them all as JPG simultaneously.
- Should I convert PNG screenshots to JPG?
- No. Screenshots contain text with sharp edges. JPG compression creates visible blurring and artifacts around text. Keep screenshots as PNG for clear, readable text.
- Is JPG better than PNG for social media?
- For photos, yes — JPG files are smaller and social media platforms often re-compress PNG photos anyway. For logos and graphics with text, PNG maintains sharper quality on social media.
- Can I convert PNG to JPG without losing the original?
- Yes. Convertify creates a new JPG file from your PNG — the original PNG is not modified. Download the JPG and keep your PNG as backup if needed.
Why convert PNG to JPG? The file size argument
PNG files are large. A 12-megapixel photograph saved as PNG can easily exceed 20MB. The same photo as JPG at high quality is typically 3-6MB — a 70-80% reduction in file size with no visible quality difference. This matters enormously for web performance (slower page loads), email (attachment size limits), storage (disk and cloud space), and sharing (upload/download speed). If your PNG contains a photograph or detailed illustration without transparency, converting to JPG almost always makes sense.
When you should NOT convert PNG to JPG
PNG is the right choice for certain types of images and converting them to JPG will visibly degrade quality. Logos and icons with sharp edges: JPG compression creates visible artifacts (halos and blurring) around hard edges. Screenshots with text: JPG compression makes text look fuzzy, especially at small sizes. Images with transparency: JPG has no transparency support — transparent backgrounds become white. Images with flat colors: PNG compresses these much more efficiently than JPG. Anything you plan to edit and re-save: JPG loses quality each save, PNG does not. For these cases, keep the PNG.
PNG vs JPG — when to use each format
| Image type | Keep PNG | Convert to JPG |
|---|---|---|
| Photographs | ❌ Too large | ✅ Ideal |
| Logos & icons | ✅ Sharp edges | ❌ Artifacts |
| Screenshots with text | ✅ Sharp text | ❌ Blurry text |
| Transparent backgrounds | ✅ Required | ❌ No transparency |
| Gradients & sky photos | ⚠️ Large files | ✅ Better compression |
| Social media photos | ⚠️ Converted anyway | ✅ Ready to upload |
| Web hero images | ❌ Slow load | ✅ Fast load |
| Print artwork | ✅ Lossless | ⚠️ Some quality loss |
JPG quality settings — finding the right balance
JPG quality is measured on a scale from 1 (maximum compression, minimum quality) to 100 (minimum compression, near-lossless). The sweet spot for photographs is 75-90, where file sizes are dramatically smaller than PNG but visual quality is indistinguishable from the original. Below 60, compression artifacts become noticeable — blocky areas, smeared details, and color banding. Convertify defaults to 80% quality, which produces excellent results for most photos. You can adjust the quality slider to find the right balance between file size and quality for your specific image. For web use, 75-80 is the standard recommendation.
PNG transparency — what happens when you convert to JPG
PNG supports full alpha channel transparency and is the standard format for images with transparent backgrounds — product photos, logos, UI elements, and cutout images. JPG does not support transparency in any form. When you convert a PNG with transparency to JPG, all transparent pixels are replaced with a solid fill color (white by default). If your PNG has a white or light background that you want to preserve, this is not a problem. If your PNG has a transparent background that you need to maintain, do not convert to JPG — use WebP or keep the PNG instead. Convertify fills transparent areas with white to match standard web behavior.
Optimizing PNG for web before considering JPG
Before converting, consider whether PNG optimization might achieve sufficient file size reduction. Tools like pngquant can reduce PNG file sizes by 60-80% by reducing the color palette — ideal for logos, icons, and simple graphics. For photographs, however, optimized PNG is still typically 3-5x larger than equivalent JPG. If you have a photograph in PNG format, JPG conversion almost always makes more sense than PNG optimization. For graphics, icons, and logos, try PNG optimization first and only convert to JPG if the result is still too large.
Batch conversion — convert multiple PNG files at once
Convertify handles batch PNG to JPG conversion for up to 10 files simultaneously. This is particularly useful when optimizing a folder of screenshot exports, converting a product photo library for web upload, preparing images for a bulk social media post, or converting design exports from Figma or Sketch. Upload all your PNG files at once, set the output quality, and download a ZIP file containing all converted JPGs. Processing happens simultaneously on the server — 10 files takes roughly the same time as 1.
How Convertify converts PNG to JPG
Convertify uses libvips with a Rust backend for PNG decoding and JPG encoding. The conversion pipeline handles PNG files with all color modes — RGB, RGBA, grayscale, indexed color — converting each correctly to the appropriate JPG color space. Alpha channel data is composited against a white background before JPG encoding. Color profiles (ICC profiles) embedded in PNG files are preserved and applied during conversion to maintain accurate colors. EXIF metadata present in PNG files is transferred to the JPG output. Your file is processed server-side over HTTPS and deleted immediately after download.
