JPG vs PNG vs WEBP vs AVIF
Four formats cover nearly every image on the internet, and picking the wrong one costs you quality or megabytes. The simple rule set: photos, graphics, transparency and web speed — each format has exactly one home turf.

Step by step
- Photo with no transparency → JPG (or AVIF/WEBP for the web, where they are smaller at the same quality).
- Graphic, screenshot, logo or anything with transparency or crisp text → PNG.
- Website image where load speed matters → WEBP first, AVIF if your audience is on modern browsers.
- When in doubt, keep a PNG or high-quality JPG master and export copies for each use.
Tips from people who do this a lot
- Converting JPG → PNG never adds quality back; it just makes the file bigger. Always convert from the best original.
- Screenshots with text go fuzzy as JPG — that is the format working as designed; use PNG.
- AVIF wins on size but encodes slowly and some older software cannot open it — keep a JPG fallback for sharing.
FAQ
Why do sites serve me WEBP when I right-click-save?
Because it is smaller for them to serve. Convert it to JPG here if your other software refuses it.
Which format is best for printing?
PNG or the highest-quality JPG you have, at full resolution — web formats optimised for size are not for print.
Is this really free?
Yes — every tool on this site is free. A short ad before your download is what pays the server bills, so nothing needs a paywall or an account.
