How to Convert Between Image Formats (JPG, PNG, WebP)
Every image format is a trade-off. JPG is small but loses detail. PNG is crisp and supports transparency but gets large. WebP does both jobs better but a few old programs still choke on it. Converting lets you pick the right format for the job rather than being stuck with whatever your camera or a website handed you. This guide explains what each format is good at and when to switch.
The formats, briefly
- JPG/JPEG — lossy, small, no transparency. The default for photographs. Bad for text, logos, or sharp edges.
- PNG — lossless, larger, supports transparency. Ideal for logos, screenshots, and graphics.
- WebP — modern, supports both lossy and lossless plus transparency, typically 25–35% smaller than JPG or PNG at the same quality. Excellent for the web.
- GIF — limited colors, supports simple animation. Largely superseded except for animations.
How to convert an image with this tool
- Open the Convert Image Format tool.
- Load your image in its current format.
- Choose the target format.
- Convert and download.
It all runs in your browser — nothing is uploaded.
Which format to pick
- Photo for the web: WebP first, JPG as a fallback.
- Logo or graphic with transparency: PNG, or WebP if the site supports it.
- Screenshot with text: PNG keeps the text crisp.
- Maximum compatibility (old software, some printers): JPG for photos, PNG for graphics.
Watch out for these
- Converting JPG to PNG does not restore quality. The detail JPG threw away is gone; PNG just stores the already-degraded image losslessly and larger.
- Converting to JPG loses transparency — transparent areas usually fill with white or black. Keep PNG or WebP if you need the transparency.
- Repeated JPG saves degrade the image each time. Convert once, from the best original you have.

If your goal is a smaller file rather than a different format, Compress Image may be all you need. Coming from an iPhone? Photos are often HEIC, which many programs cannot open — HEIC to JPG handles that specific case. To strip hidden camera data during conversion, pair with Remove EXIF.
Common uses
- Make web images smaller by moving to WebP.
- Add compatibility by converting an odd format to JPG or PNG.
- Preserve transparency by choosing PNG over JPG.
