PNG, JPG and WebP compared
PNG
Lossless and transparent-capable. Every pixel survives conversion untouched, which makes PNG ideal for logos, icons, screenshots, and any graphic with hard edges or flat colour. The cost is size: a photograph stored as PNG is often five to ten times larger than the same image as JPG.
JPG
Lossy, no transparency, and supported by essentially every device and application ever made. It compresses photographic detail very efficiently, but struggles with sharp text and flat graphics, where it produces visible halos.
WebP
Lossy or lossless, with transparency support, and typically 25–35% smaller than JPG at equivalent quality. Every current browser supports it. The one caveat is older desktop software, some of which still cannot open a WebP file.
What gets lost along the way
Converting to PNG is always lossless. Converting to JPG or WebP re-encodes the image and discards some detail permanently. Crucially, that loss compounds: converting a JPG to WebP and back to JPG applies lossy compression twice. Always start from your original file rather than from a previous conversion.
Metadata is also dropped. Canvas-based conversion produces a clean image without EXIF data, which means camera model, timestamps and GPS coordinates are stripped out. That is often exactly what you want before sharing a photo publicly.
Common conversions
- PNG to JPG — shrinking screenshots or photos saved in the wrong format. Transparency is flattened onto the background colour you pick.
- JPG to WebP — cutting page weight on a website without a visible quality drop.
- WebP to PNG — getting a file into older software that cannot read WebP.
- PNG to WebP — keeping transparency while cutting file size, ideal for web graphics.
Frequently asked questions
Which format should I choose?
WebP is the best default for the web — typically 25–35% smaller than JPG at equivalent quality, with transparency support. Use JPG for maximum compatibility with older software, and PNG when you need lossless quality or crisp transparent edges on graphics and logos.
Will converting PNG to JPG lose transparency?
Yes. JPG has no alpha channel, so transparent areas are filled with a solid background — white by default in this tool. If you need transparency and a smaller file, convert to WebP instead, which supports both.
Does converting reduce image quality?
Converting to PNG is lossless and preserves every pixel. Converting to JPG or WebP re-encodes the image, so some detail is discarded. Converting repeatedly between lossy formats compounds that loss, so always convert from your original file rather than from a previous conversion.
Can I convert HEIC files from my iPhone?
Only if your browser can decode HEIC, which Safari on Apple devices can and most other browsers cannot. On unsupported browsers the file will fail to load. Exporting as JPG from the Photos app first is the reliable route.
