Convert between JPG, PNG and WebP in your browser. No upload, no queue — the file stays on your device.
Convert between JPG, PNG and WebP without uploading the file anywhere.
How to convert an image format
Choose a file, pick the target format (PNG, JPG or WebP), then press Download converted image. The conversion is done on a canvas in your browser.
When to use each format
PNG for lossless graphics, screenshots and transparency. JPG for photos where smaller files matter. WebP gives the smallest files with good quality and is supported by all modern browsers.
Frequently asked questions
Can I convert WebP to JPG?
Yes — any of the three formats can be the source or the target.
Is my image uploaded?
No. Everything happens locally in the page.
Will converting to JPG lose transparency?
Yes, JPG has no alpha channel; transparent areas become white. Use PNG or WebP to keep transparency.
How to use it
- Select an image file from your computer. The page accepts PNG, JPG, and WebP files as source images.
- Pick one of the three format options: PNG, JPG, or WebP. Changing the option updates the preview immediately.
- If you choose JPG or WebP, adjust the quality slider to control file size. Higher quality keeps more detail; lower quality shrinks the file.
- Click Download converted image. The browser saves the new file with the selected format extension.
Where it comes in handy
A blogger exports a 3.2 MB PNG screenshot down to 480 KB as a WebP image. The page loads faster on mobile without visible quality loss at 92% quality.
An online shop has 12 product photos in PNG format averaging 1.4 MB each. Converting all 12 to JPG at 85% quality brings the total storage from 16.8 MB down to about 3.6 MB.
A developer needs to serve icons with transparency to an older browser that does not support WebP. The PNG stays for those cases, while the WebP version handles modern visitors, cutting average icon file size from 18 KB to 7 KB.
Worth knowing
- Converting a transparent PNG to JPG replaces the alpha channel with a white background. Any transparent or semi-transparent edges become solid white after conversion.
- When you switch from a higher-quality setting to a lower one, the quality slider rounds to whole percentages. A change from 92% to 88% jumps in 4-point steps, so fine-tuning between those values is not possible.
- PNG output does not include a quality control option. PNG uses lossless compression, so the file size depends entirely on the original image data and whether the source contained transparent areas.
