Image Format Converter
Turn one image into JPG, PNG, WebP, BMP, ICO and PDF at once.
Runs in your browser. Your images are never uploaded.
Drop an image to convert it to every format at once
JPG, PNG, WebP, GIF, BMP or SVG — or a ZIP of them.
Need several images in one PDF? Use Images to PDF. Converting hundreds of photos to a single format? Use the Batch Image Converter.
Choosing a format
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| WebP | Lossy | Yes | Almost everything on the web |
| AVIF | Lossy | Yes | The smallest files, where browser support allows |
| JPG | Lossy | No | Photos, and anywhere that asks for JPG |
| PNG | Lossless | Yes | Screenshots, logos, text, line art |
| ICO | Lossless (PNG inside) | Yes | Website favicons and Windows icons |
| BMP | None | No | Old Windows software that needs it |
| Lossy (JPG inside) | No | Printing, emailing, or uploading where a PDF is required |
Why convert to several formats at once
The best format depends on the image. A photo usually comes out smallest as WebP, while a flat-colour logo can be smaller as PNG than as either lossy format. Rather than guess, convert to all of them and compare their sizes.
It also saves repetition when one image has to go to several places — a WebP for your website, a JPG for a form that insists on it, an ICO for the favicon, and a PDF for someone who wants to print it.
What conversion does and does not change
Conversion re-encodes the pixels into a different format. It cannot add detail that is not there, so a JPG converted to PNG carries its existing compression artefacts into a larger, lossless file — the image does not improve, only the file size grows. Converting between lossy formats compounds the loss, so if you edit an image repeatedly, keep a lossless master and export lossy copies at the end.
Frequently asked questions
Can I convert one image to several formats at once?
Yes — that is what this tool is for. Tick every format you want, drop the image in, and each version is produced side by side with its file size, so you can download just the one you need or all of them as a ZIP. Change the quality or the formats and the results update straight away.
Can I paste a screenshot instead of saving it first?
Yes. Copy an image or take a screenshot, then press Ctrl+V (⌘V on a Mac) anywhere on this page and it is converted straight away. On a phone or tablet, use the Paste image button instead. Pasted images are named with the date and time so repeated pastes never overwrite each other.
Which image format should I convert to?
WebP for the web in almost every case: it is 25 to 35% smaller than JPEG at equivalent quality, supports transparency, and every current browser displays it. Keep PNG where you need exact pixels — screenshots, logos, line art, anything with sharp edges or text. Use JPEG where a site, form or app specifically asks for it.
How does the ICO favicon work?
The ICO file bundles several sizes of the same icon — 16, 32, 48, 64, 128 and 256 pixels, up to the size of your image — so browsers and Windows each pick the sharpest one. A non-square image is centred on a transparent square rather than cropped. For a crisp favicon, start from a square image at least 256 pixels wide.
Does converting PNG to JPEG lose my transparency?
Yes, because JPEG, BMP and PDF pages have no transparency. Transparent areas are filled with the background colour you choose in the settings, which is white by default. WebP, PNG and ICO keep transparency intact.
Why does my converted file sometimes get bigger?
Usually because you converted from a lossy format to a lossless one, where the encoder must now preserve the JPEG's own artefacts as if they were real detail. Converting a photo to PNG routinely triples its size, and BMP is not compressed at all.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser — the files never leave your device, and nothing is kept after you close the tab. That is also why the only size limit is your own device's memory.
What happens to EXIF metadata and colour profiles?
Both are dropped. The image is redrawn from its pixels, so camera details, GPS coordinates and embedded colour profiles do not carry over. That is usually welcome for privacy, but keep your original if you need the metadata, and expect a slight colour shift for images in a wide-gamut profile.
