A resizer and compressor in one

Sometimes you need an image at a precise pixel size — a 1200px banner, a 512px icon, a 300px thumbnail. Other times you need a precise file size. PixelPress does both at once: set the dimensions, set the KB target, and get a single optimised file.

Lock the aspect ratio

Each image has a lock button between the width and height fields. When it's on, changing one dimension updates the other automatically so your picture never looks stretched. Turn it off only when you deliberately want a different shape.

Batch resizing

Add a whole folder of images, give them the same output settings, and compress them together. Download each one individually, or grab them all in a single ZIP.

Private and instant

There's no queue and no upload. Because the resizing runs on your own device with the Canvas API, results appear almost instantly and your files stay completely private.

FAQ

Frequently asked questions

Everything about compressing images to an exact size.

How do I resize to specific dimensions?

Add an image, then type the Width and Height you want. Keep the lock enabled to preserve the aspect ratio automatically, or unlock it to set both freely. Press Compress to render the resized image.

Can I resize and compress at the same time?

Yes — that's the point. Set your pixel dimensions and a KB target together, and PixelPress produces an image that matches both as closely as possible.

Does resizing upscale images?

You can enter larger dimensions, but enlarging a small image can't add detail that isn't there. For best quality, resize down rather than up.

Which formats are supported?

Input: JPG, PNG and WebP. Output: JPG, PNG or WebP. So the resizer also works as a converter.
