How it works
Upload
Drop a JPG, PNG, or WebP into the box above — or click to browse. The image is read locally; nothing is uploaded.
Pick a format
Choose JPG, PNG, or WebP from the dropdown. For JPG and WebP, drag the quality slider — the transparency warning appears if JPG would flatten your alpha channel.
Download
Hit "Convert & download" and save the new file with its proper extension. Repeat for as many images as you like — no sign-up, no limits.
JPG vs PNG vs WebP — which should you choose?
- JPG — best for photos. Tiny files for complex, colorful images; no transparency support. The universal default: every device, app, and upload form on earth opens it.
- PNG — best for graphics and transparency. Lossless quality for logos, screenshots, text, and line art. Heavier than JPG for photos, so don't use it for camera shots.
- WebP — the modern best of both. Roughly 25–35% smaller than an equivalent JPG with transparency support included. All modern browsers (Chrome, Edge, Firefox, Safari 14+) open it natively.
Rule of thumb: photos go to JPG or WebP; graphics and anything with transparency go to PNG or WebP; and when a stubborn form rejects everything else, JPG is the maximum-compatibility answer.
Tips
- Converting JPG to PNG doesn't restore quality. Compression discards detail permanently — PNG just preserves what's left, in a bigger file.
- Quality 80–90 is the sweet spot for photos. Visually identical to 100% at a fraction of the file size.
- Watch the transparency warning. If you're converting a PNG logo to JPG, transparent areas become white — pick WebP instead to keep the alpha and still save space.
- WebP to JPG for stubborn uploaders. Some older forms and desktop apps still reject WebP; one click here fixes it.
- Keep your originals. Conversion is one-way for quality — archive the source before you commit to a lossy format.
Common uses
Format conversion solves those small compatibility headaches that interrupt real work. Turn bulky PNG screenshots into lightweight JPGs before attaching them to emails. Convert WebP images downloaded from the web into JPGs for older software that can't open them. Shrink PNG logos to WebP so your website loads faster without losing transparency. Prepare photos for platforms that only accept JPG uploads. Or batch-convert a folder of mixed formats into one consistent format before handing files to a designer or printer.
