Image Converter

Convert images between formats without uploading them

Most format problems are the same problem: a file that one device made and another will not open. An iPhone saves HEIC, a website hands you WebP or AVIF, and the form, editor or person at the other end wants a JPG or a PNG. This page takes the image you have and writes the same picture out in the format you need.

It runs entirely in your browser. The image is decoded on your device, drawn once, and encoded again, so nothing is uploaded and the result is ready as fast as your computer can produce it. Free, unlimited, no signup, no watermark.

How to use it

1. Add your images. Drop them on the panel above, pick files from your device, or paste from the clipboard. Up to 50 at once, 50 MB each.
2. Choose the output format. JPG, PNG, or WebP where your browser can write it.
3. Adjust quality if you want to. For JPG and WebP the slider starts at 90. For JPG you can also set the colour that replaces transparent areas.
4. Check each row. You see the size before and after and the pixel dimensions, plus a note if an image had to be reduced or only the first frame of an animation was kept.
5. Download. Save files one at a time, or use Download all for the whole batch.

Which output format to choose

• JPG is the safe choice for photographs. Every device, app and upload form reads it. It is lossy and has no transparency, so see-through areas are filled with a colour you pick.
• PNG is lossless and keeps transparency. Use it for logos, screenshots, diagrams and anything you will edit again. Photographs come out much larger than as JPG.
• WebP is smaller than JPG at the same quality and keeps transparency, which suits images for a website. It is offered only in browsers that can encode it, and Safari is not one of them.

What it does not do

• It does not keep animations. An animated GIF, WebP or AVIF gives you its first frame, and the row says so.
• It does not keep metadata. EXIF details such as location and capture time are not written to the new file.
• It does not hide a size change. Where a browser cannot hold a very large image, mainly on iPhone and iPad above about 16.7 megapixels, the image is reduced and the row shows the new dimensions.
• It does not write HEIC or AVIF. Those are formats to convert from; the output is JPG or PNG, or WebP in a browser that can write it.

Your images stay on your device

Converters that work by upload hold a copy of every file you give them, for however long their retention policy says. This one has no upload step to begin with. Decoding and encoding happen in this tab, no request carries your image anywhere, and closing the page discards everything. That matters for the files people most often need to convert: phone photos with a location inside them, scans of documents, and unreleased work.

Image converter questions

Are my images uploaded to a server?

No. Each image is decoded and re-saved by your own browser. It never leaves your device, nothing is uploaded, and there is no copy for us to store or delete. That is also why there is no queue: the work starts the moment you drop the file.

Which formats can I convert from?

HEIC and HEIF photos from iPhones and other phones, AVIF, WebP, PNG, JPG, GIF, BMP and SVG. Everything except HEIC is opened by the decoder built into your browser. HEIC is opened by Safari on its own; in Chrome, Firefox and Edge the page fetches a HEIC decoder the first time you add one, a single 3.2 MB download.

Which formats can I convert to?

JPG and PNG in every browser, and WebP in browsers that can write it. Safari cannot encode WebP, so the WebP option is simply not shown there instead of quietly handing you a different format.

Should I pick JPG, PNG or WebP?

JPG for photographs and for anything going into an upload form, because everything accepts it and the files are small. PNG when the image has a transparent background, or is a screenshot, logo or diagram with sharp edges, because it is lossless. WebP when the picture is going onto a website and you want the smallest file with transparency intact.

What happens to transparent backgrounds?

PNG and WebP keep them. JPG has no transparency, so transparent areas are filled with the background colour you choose, white by default. That goes for every format the tool opens, a HEIC with see-through areas included.

How many images can I convert at once?

Up to 50 per batch, each up to 50 MB. They are converted one at a time, each with its own status and download button, and a file that fails does not stop the others. There is no signup, no watermark and no daily limit, so run as many batches as you need.

What happens to animated GIF, WebP or AVIF files?

Only the first frame is converted, and the row for that file says so. The converter writes still images and does not produce animated output.

Are very large images kept at full size?

Yes, up to 16,384 pixels a side wherever the browser can hold a canvas that large, which covers every phone camera. Browsers on iPhone and iPad stop at about 16.7 megapixels, so a larger image is reduced there and its row shows the size it was reduced to. Nothing is ever shrunk without telling you.

Is the metadata kept?

No. The new file is written from the pixels alone, so EXIF data such as the GPS location, capture time and camera model is not carried over. Keep the original if you need that information.
