Convert a batch of images between PNG, JPG and WEBP in your browser — no upload, no sign-up, no watermark. The file name stays the same, only the format changes.
Free, no sign-up, runs in your browser. Your images never leave this device.
PNG, JPG, WEBP, GIF or AVIF, at most 20 MB each, at most 20 images at a time. Nothing is uploaded. HEIC files cannot be read here — see the HEIC note below.
HEIC? Most browsers cannot read HEIC photos from iPhones. Change your iPhone to save JPG (Settings → Camera → Formats → Most Compatible) or convert the HEIC first — see below.
Quality applies to JPG. Transparent areas become pure white (#FFFFFF), because JPG has no transparency.
Your converted images will appear here, with the size before and after.
| Format | Transparency | Quality | Best for |
|---|---|---|---|
| JPG | No — transparent areas become white #FFFFFF | Lossy, set by the quality slider | Photos, and anything that must open everywhere |
| PNG | Yes — kept exactly | Lossless, quality slider does nothing | Logos, screenshots, graphics with transparency |
| WEBP | Yes — kept | Lossy or lossless, set by the quality slider | The web — about 25–35% smaller than JPG at the same quality |
JPG for photos and anything that must open everywhere; PNG for logos, screenshots and anything with transparency that must stay lossless; WEBP for the web — about 25–35% smaller than JPG at the same quality. An animated GIF keeps only its first frame when converted. Converting a JPG to PNG does not restore quality the JPG already lost.
Most browsers cannot read HEIC files. Only Safari on Apple devices opens them; Chrome, Firefox and Edge do not. That is why this tool refuses HEIC files in every browser, instead of working in one browser and failing silently in another.
Renaming a file from .heic to .jpg does not convert it — the file inside is still HEIC, and it still will not open. The photo itself has to be converted first, then dropped here as a JPG.
No. Everything happens in your browser with canvas: the image is read, converted and downloaded on your device. You can check the browser network tab: there is no upload.
JPG has no transparency, so transparent areas become pure white (#FFFFFF). If you want to keep transparency, convert to PNG or WEBP instead.
Most browsers — Chrome, Firefox and Edge — cannot read HEIC files; only Safari on Apple devices opens them. That is why this tool refuses HEIC in every browser. On your iPhone, go to Settings → Camera → Formats → Most Compatible so new photos are saved as JPG. For a HEIC you already have, share it by email or message (the iPhone converts it to JPG when sharing) or open it in Preview on a Mac and choose File → Export as JPEG.
The pixel size does not change: this tool only changes the format. JPG and WEBP lose a little quality according to the quality slider; PNG loses none. The file can come out smaller or bigger: a JPG saved as PNG almost always weighs more, and the page shows the difference for every image.
Yes. They are your images, and the tool adds no watermark and changes no licence. To make a brand-new image with AI or remove a background, use the Movapix app: about $0.008 per image.
This tool only converts what you already have. To make a brand-new product photo from one sentence, or remove a background, use the app — about $0.008 per image, credits never expire.
Your images are private by default. This page sends nothing anywhere.
