Image Resizer

Resize, crop, rotate and compress pictures – right here in your browser. Your files are never uploaded anywhere, so there is no size limit and nothing leaves this computer. Set an exact width and height, a percentage, a ready-made social size, or simply a target file size in KB for online form uploads. Save as JPG, PNG with a transparent background or TIF for the press.

1. Add pictures

JPG, PNG, WEBP, GIF, BMP or AVIF.

2. Resize settings

Applies to every picture in the list.

With the ratio locked, type either a width or a height – every picture keeps its own shape. Unlock it to force an exact width and height. Leave both empty to keep the original size and only change the format or quality.

When the shape does not match

3. Export settings

Format, quality and file size.

Target file size is useful for exam and application forms – type 50 KB and the quality is adjusted automatically until the picture fits. If it still will not fit, the picture itself is made a little smaller.

Finishing

The background colour shows through where a PNG was transparent, and in the border left by “Fit inside”.

Add a few pictures on the left and they will appear here.
Hover any picture to crop it, rotate it or remove it.
Nothing is uploaded. Every picture is resized inside this page using your own computer, so photographs of children, staff records and unpublished book artwork stay private. Large pictures are reduced in gentle steps so the result stays sharp instead of looking jagged.
