JPG vs PNG vs WEBP: Full Comparison

Quick Comparison

JPG In Depth

JPG uses lossy compression — each save discards some pixel data to reduce file size. For photographs, this trade-off is invisible at normal viewing sizes. JPG is the best choice when you need the smallest file for a realistic photo and do not need transparency.

Use JPG for: Photographs, product images, social media uploads Avoid JPG for: Logos, text overlays, graphics that will be edited repeatedly

PNG In Depth

PNG uses lossless compression — every pixel is stored exactly as-is. This produces perfect quality but larger files. PNG supports full alpha transparency, making it essential for logos and UI elements.

Use PNG for: Logos, screenshots, icons, images needing transparent backgrounds Avoid PNG for: Full-bleed photographs on high-traffic web pages (too large)

WebP In Depth

WebP was developed by Google to combine the best of JPG and PNG. It supports both lossy and lossless modes, has full transparency support, and produces files 25–35% smaller than JPG at equivalent quality.

Use WebP for: All web images — product photos, banners, thumbnails, backgrounds Avoid WebP for: Files that need to be opened in software that does not yet support WebP

How to Convert

• PNG to WEBP
• PNG to JPG
• JPG to PNG

The Core Differences

JPG: Lossy compression. Best for photos and complex-colour images. Does not support transparency. Universal browser and device support. Ideal for sharing and web photos.

PNG: Lossless compression. Best for graphics, screenshots, and images with text or sharp edges. Supports transparency (alpha channel). Larger file size than JPG for photographic content. Universal support.

WebP: Both lossy and lossless modes. Best of both worlds for web use. Supports transparency. 25–35% smaller than JPG or PNG at equivalent quality. Supported by all modern browsers (Chrome, Firefox, Edge, Safari 2020+). Not supported by some older tools.

File Size Comparison

For a 1200×800 photo:

• PNG: ~1.5–2 MB (lossless)
• JPG (quality 85%): ~200–350 KB (lossy)
• Lossy WebP (quality 80%): ~150–250 KB (lossy, better quality per byte than JPG)

For a 400×400 logo with transparency:

• PNG: ~15–80 KB (depends on colour complexity)
• Lossless WebP: ~10–60 KB (~25% smaller than PNG)
• JPG: Not applicable (no transparency)

Which Format for Which Use Case

Portrait photos, product photos, event photos for sharing: JPG or lossy WebP

Logo for a website (needs transparent background): PNG or lossless WebP

Screenshot of a user interface: PNG (lossy compression creates artifacts around text)

Blog featured image: Lossy WebP (with JPG fallback for older browsers)

Icon or small UI element: PNG or SVG (for scalable icons)

Photos for government portal upload: JPG (universal compatibility)

iPhone photos for non-Apple recipients: Convert HEIC to JPG first

Converting Between Formats

All conversions are available on weFixPDF:

• PNG to JPG (for smaller file size)
• JPG to PNG (for lossless editing or transparency support)
• PNG to WebP (for web performance)
• HEIC to JPG (for cross-platform sharing)

All conversions run in your browser — files are never uploaded to a server.

Quick Reference

For uploading to government portals in India: JPG — universally accepted, smaller than PNG, no compatibility issues.

For a website logo with transparent background: PNG or lossless WebP.

For web performance optimization: WebP (lossy for photos, lossless for graphics) — smaller than JPG and PNG with equivalent quality.

For iPhone photos shared with non-Apple users: Convert HEIC to JPG first — HEIC is not compatible with most devices and portals.

For archiving images you'll edit in the future: PNG — lossless, no degradation across saves.
