Photo converter
Convert your photos to and from the most common image formats — HEIC, PNG, JPG, WebP, TIFF, BMP, GIF and ICO. Drop in several at once, choose one output format, and take them one by one or all together as a ZIP. It happens in your browser; nothing is uploaded.
Most common formats, both ways
Read: HEIC/HEIF, PNG, JPG, WebP, AVIF, GIF, BMP, ICO, SVG and TIFF. Write: JPG, PNG, WebP, TIFF, BMP, GIF and ICO. So you can go from almost anything to almost anything — an iPhone HEIC to JPG, a scan to TIFF, a logo to ICO, a photo to WebP. Drop in up to five files at once; they all come out in the format you picked, and you can take them one at a time or all together as a ZIP or TAR.GZ.
About HEIC — the iPhone's own photo format. Your iPhone, iPad and Mac can read HEIC themselves, so open this page on the device the photos are already on and it simply works. A Windows or Android browser has no HEIC reader built in, and Apple's is not ours to hand out, so there you get a clear message instead of a file that quietly fails. Same rule as our GIF maker: when something came off a phone, the phone is the shortest road.
Which image format should you actually use?
Most people convert an image because something refused to open it, and the fix is usually one of five formats. JPEG is for photographs going to people: small files, no transparency, and every device on earth reads it. PNG is for anything with sharp edges, text or transparency — logos, screenshots, diagrams — and it is lossless, so it never degrades. WebP is the modern middle ground: roughly 25 to 35% smaller than JPEG at the same visible quality, with transparency, and supported by every current browser. TIFF is the print and archive format, lossless and large. ICO exists for one job only: a website or application icon.
HEIC and AVIF: the same idea, two very different licences
HEIC and AVIF do the same job — roughly half the size of a JPEG at the same visible quality — and they were built the same way, by wrapping a modern video codec around a single still frame. The difference is legal, and it explains everything you run into in practice. HEIC uses HEVC, which is covered by patent pools that charge per copy of any software that decodes it, which is why Windows will not open an iPhone photo out of the box and why converters that do open it are quietly taking a risk. We deliberately do not ship a decoder: your Apple device already has one that Apple licensed properly, so we hand the file to it. AVIF is the royalty-free answer to exactly that problem — same container family, but built on AV1, which anyone may implement without paying anyone. It reads everywhere here, and if you get to choose a modern format yourself it is the one without strings attached.
Lossy or lossless, and what the quality slider really does
PNG, TIFF and BMP are lossless: the pixels that come out are the pixels that went in, and you can convert back and forth forever without damage. JPEG and WebP are lossy: they discard detail your eye is unlikely to miss, which is exactly why they are small. The quality slider decides how much gets discarded, and the useful range is narrower than it looks — around 80 to 90 is nearly always right, because below 75 the artefacts start to show on edges and above 95 the file grows fast for a difference nobody can see. One thing worth knowing: every save of a lossy format throws away a little more. Converting a JPEG to a JPEG five times will visibly damage it, so always go back to the original when you can.
Transparency: which formats keep it and which cannot
PNG, WebP, TIFF, GIF and ICO can store transparency. JPEG and BMP simply cannot — the format has no way to record it. When you convert something transparent to one of those, this tool fills the see-through parts with white rather than letting them turn black, which is what a naive conversion usually does. GIF is the odd one out: it can be transparent, but only completely, with no half-transparent pixels, so a soft edge becomes a hard one. If your image has a transparent background and you are not sure where it is going, PNG is the safe answer.
Converting a whole batch at once
Drop in as many photos as you like, choose one output format, and take them one at a time or all together as a ZIP. The free tier covers five images per batch and five per day, at up to 10 MB each, which is enough for a holiday set or a product listing. One broken or unsupported file no longer kills the whole batch: it is reported by name and the rest go through. If you are converting to shrink files rather than to change format, the image compressor is the better tool — it shows you the before and after size.
Why none of this touches our server
The entire conversion runs on your own processor, inside the browser tab. Your photos are never uploaded, which is not a policy we ask you to trust but simply how the tool is built — you can watch the network tab and see that nothing leaves. That also explains why it is instant and why there is no queue: your device does the work. The only limit is your device itself, so a very large TIFF on an old phone will be slower than on a laptop.
Converting images without an upload
Pick your files, pick the one format you want them all in, and download the results. Your photos never leave the device — the conversion runs on your own processor, which is also why it is instant and free. WebP usually gives the smallest files at equal quality; PNG and TIFF stay lossless.
Does it stay lossless?
PNG, TIFF and BMP are lossless — the picture that comes out is the picture that went in. JPEG and WebP compress; the slider controls the trade-off between file size and quality. The slider disappears for the formats that ignore it, so it never pretends to do something it cannot.
Why does my transparent PNG come out with a white background?
Because JPEG and BMP have no transparency — the format itself cannot store it, so we fill the see-through parts with white rather than let them turn black. If you need the transparency kept, choose PNG, WebP, TIFF, GIF or ICO.
Can I convert several photos at once?
Yes — drop in up to five at a time and they are all converted to the one format you picked, whatever they were before. You can download them one by one, or press Download all for a single ZIP (or TAR.GZ). Each converted photo counts as one of your free images for the day.
