Resize images without uploading them

Get the exact size you needed, first try

Most resizers make you guess. You type a number, get back a square with white bars down the sides, and start over. Here you fill in one side and the other is calculated from your image's own proportions. Nothing is stretched, nothing is cropped, nothing is padded.

Give both sides and they describe a box: the image is scaled until it fits inside. A 3000 × 2000 photo asked for at 800 × 600 comes back as 800 × 533, because the width runs out first, and you get no bars to crop off afterwards.

Nothing you drop here is uploaded

Every other tool in this category sends your files to a server, does the work there, and sends them back. That means waiting twice, and it means your images sitting on someone else's disk. This one works the other way around: the code runs inside your browser, on your own processor. Close the tab and nothing of them exists outside your device.

One side effect is worth knowing about: because every output is re-encoded from scratch, the metadata does not survive. GPS coordinates, camera model, date and time: all of it is dropped from the file you download. If you were about to post a photo publicly, that is usually exactly what you wanted.

It refuses the two things that would make your image worse

It never enlarges. Ask for 1200 from a 400 px source and there is no extra detail to invent, so you would get a blurrier file, not a better one. You are told so as soon as the file is read, before anything runs, and you get the source size instead.

And it does not quietly change your format. A JPEG stays a JPEG. A PNG stays a PNG, so a logo with a transparent background does not come back sitting on a white rectangle. The format only changes when you explicitly ask for a white ground under a cut-out.

How to resize an image

1. Set the size you need. Type a width, a height, or both. Leave a field empty and that side is left free.
2. Drop your images. One or fifty, JPEG, PNG or WebP, up to 25 MB each. Processing starts on the drop. There is no button to hunt for and nothing to confirm.
3. Take the results. Download them one by one, or grab the whole batch as a single zip.

Frequently asked questions

How do I resize an image without losing quality?

Make it smaller, never bigger, and re-encode once. Both are what happens here: the scaling is done at high interpolation quality in a single pass, and enlarging is refused outright rather than faked. A JPEG is re-encoded at quality 0.9; a PNG stays lossless.

Is there a free image resizer that does not make me upload anything?

This one. There is no upload step at all, no account, no watermark and no per-image limit beyond the batch size. It is paid for by discreet ads, not by your files.

Can I resize a lot of images at once?

Up to 50 in one batch, and they come back as a single zip. If that is your main job, the bulk resizer page covers the batch specifics: timings, memory and naming.

Which formats can I use?

JPEG, PNG and WebP go in. JPEG comes out for a JPEG source; PNG comes out for PNG and WebP sources, so that a possible transparency is never flattened without you asking.

Does resizing strip the photo's metadata?

Yes, and deliberately. The output is a freshly encoded file, so EXIF data, including the GPS position your phone wrote into it, does not carry over.
