How to Convert an Image Format
- Upload your image above (any format: JPG, PNG, WebP, GIF, HEIC, etc.).
- Select the output format you want.
- Click "Convert" and download your converted file.
Choosing a Format: Three Questions
Almost every format decision comes down to three things, in this order. First: does the image need transparency? If yes, JPEG is out entirely — it has no alpha channel and will fill any transparent area with solid white. That leaves PNG and WebP.
Second: is it a photograph, or a graphic? Photographs are continuous-tone — smooth gradients, no hard edges — and lossy compression handles them extremely well. Graphics, logos, screenshots and anything containing text are the opposite: large flat areas with sharp boundaries, which lossy compression visibly damages while barely reducing the size.
Third: where is it going? Browsers read everything, so WebP is the efficient choice for websites. Email clients, print services, upload portals and older desktop software are far more conservative, and JPEG or PNG remain the safe answers there. The right format is rarely the technically best one — it is the best one your destination actually accepts.

| Your image is | For the web | For email or print | For editing |
|---|---|---|---|
| A photograph | WebP | JPG | PNG or original raw |
| A logo with transparency | WebP | PNG | SVG if available |
| A screenshot with text | PNG or WebP lossless | PNG | PNG |
| A scanned document | JPG | JPG or PDF | PNG |
| A simple icon | SVG, else PNG | PNG | SVG |
| An animation | WebP or GIF | GIF | Source project file |
Converting Between Lossy Formats Costs Quality Every Time
JPEG and lossy WebP both work by discarding detail. Converting a JPEG to WebP means compressing an already-compressed image a second time, and the losses stack — the encoder cannot tell the difference between real detail and artifacts left by the previous pass, so it faithfully preserves the artifacts while discarding more genuine detail. At sensible quality settings this is invisible and perfectly fine. But if you still have the original camera file or the export from your design tool, always convert from that instead. One generation of compression beats two, and the result will be both cleaner and smaller.
Conversions Worth Making, and Ones That Are Not
- ✓PNG photographs to JPG or WebP — often 80% smaller
- ✓JPG to WebP for anything served on a website
- ✓HEIC to JPG so files open outside the Apple ecosystem
- ✓WebP to JPG or PNG when software refuses to open the file
- ✓SVG to PNG for documents and slide decks
- ✕JPG to PNG hoping to recover lost quality — it cannot
- ✕PNG screenshots to JPG — barely smaller, visibly worse
- ✕Converting back and forth between lossy formats repeatedly
- ✕WebP to PNG for a photo destined for a website
