Image Converter
Convert JPG, PNG and WebP images (plus GIF and BMP input) to the format you need, many at once. Conversion runs in your browser, so your images never leave your device and are not uploaded to a server.
Choose images, pick a format and tap Convert.
JPG vs PNG vs WebP
| Feature | JPG | PNG | WebP |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless (this tool uses lossy) |
| Transparency | No | Yes | Yes |
| Photo file size | Small | Very large (several times JPG) | Smallest (about 25–35% smaller than JPG) |
| Text, charts, logos | Edges can blur | Sharpest | Fairly sharp |
| Compatibility | Everywhere | Everywhere | Modern browsers and apps; some government forms and older software reject it |
| Best for | Photos, form uploads | Screenshots, logos, transparent images | Website and blog images |
GIF and BMP can be opened but not chosen as output. Only the first frame of an animated GIF is converted. AVIF is left out because browsers can't reliably save it yet.
Common conversions and what to watch for
- PNG to JPG: the usual fix when a screenshot or a photo saved as PNG is too big, or a form only accepts JPEG. The file shrinks a lot, but transparent areas are filled with the background color. Some programs show unfilled transparency as black, so this tool fills with white by default.
- WebP to JPG: images saved from websites are often .webp, which Word, older photo editors and many upload forms don't accept. Converting to JPG solves that.
- JPG to PNG: only the container changes; quality does not improve. Detail lost to JPG compression doesn't come back and the file gets bigger, so do this only when an editor or print service requires PNG.
- JPG to JPG (re-saving): every save adds a little more compression loss. If the goal is a smaller file, the image compressor with a target size is the better tool.
Frequently asked questions
Are my files uploaded?
No. Conversion uses your browser's canvas feature on your own device. Images are never sent to or stored on a server.
Why can't I save WebP on iPhone or Mac Safari?
Safari can display WebP images but doesn't let web pages save them as WebP. In that case the tool automatically saves JPG (or PNG for transparent images) and tells you in the result. If you need WebP files, convert in Chrome, Edge or Firefox.
Can I convert HEIC (iPhone photos) to JPG?
When you choose photos on an iPhone, iOS usually hands them over as JPEG, so they convert normally. A .heic file copied to a computer may not open in every browser; if it doesn't, the tool shows a message explaining what to do.
Does converting change the pixel dimensions?
No, width and height stay the same. To change them, use resize image. Newly saved files don't include location or camera data (EXIF).
