Resize an image to any size.
Pick a size below or type your own — in pixels, inches, centimetres or millimetres — then export as PNG or JPG. The picture is opened, resized and saved on this device, never uploaded.

Features
Everything the job usually needs
Any size you like
Type exact pixels, scale by a percentage, or pick a common size. Lock the ratio and the other side follows.
Pixels or print units
Work in px for screens, or in inches, centimetres, millimetres and points for print — at 72, 150, 300 or 600 PPI.
Opens what your phone takes
JPEG, PNG, WebP and GIF, plus the HEIC and HEIF files an iPhone saves — decoded here, not on a server.
Export as PNG or JPG
PNG stays lossless and keeps transparency. JPG has a quality slider, and you can see the file size before you save.
Fill, fit or stretch
When the shape does not match, crop to fill, pad to fit in a colour you choose, or force the size outright.
Live result
The preview is the real output, re-rendered as you change the controls — not an approximation of it.
Nothing to sign up for
No account, no email, no limits to unlock. Open the page and resize.
Privacy
Private because of how it is built
Picsizer has no upload step. When you choose a picture, the browser decodes it, resizes it on a canvas and hands the result straight back to you. There is no route on any server that accepts an image, because the image never needs to go anywhere.
- Your picture stays in this tab and is discarded when you close it.
- No account, no cookies for tracking, no image analytics.
- HEIC files are decoded here too — the decoder is downloaded to your browser, the photograph is not sent away.
Images uploaded
The file never leaves your device.
Images stored
There is nowhere for Picsizer to keep one.
Accounts needed
No sign-up, no email, no limits.
Servers involved
The resizing runs in your browser.
