How to resize an image

Select your images — JPG, PNG, WebP, GIF or BMP, one or many. They upload over an encrypted connection.
Choose a scale percentage (e.g. 50% for half size), or type an exact width and height in pixels.
Set just the width or just the height to keep the original proportions — the other side is calculated for you.
Click resize and download. Each image is returned in its original format, ready for the web, email or print.

Resize image — frequently asked questions

How do I resize an image to an exact pixel size?: Leave the Scale (%) field blank and type your target Width and Height in pixels. If you fill in both, the image is resized to exactly those dimensions. Maximum supported size is 8000 × 8000 px per image.
How do I resize by percentage instead of pixels?: Enter a value in Scale (%) — 50 makes the image half its current size, 200 doubles it. The percentage applies to both width and height, so the proportions never change. Leave the width and height boxes empty when scaling by percentage.
How do I keep the aspect ratio so the image isn't stretched?: Set only one side — either Width or Height — and leave the other blank. The tool computes the missing dimension automatically so the image stays in proportion. Scaling by percentage also preserves the aspect ratio.
What size should I resize images to for web, email, social or print?: For web pages and email, 1200–1920 px on the long edge is usually plenty and keeps files light. Social platforms favour specific sizes (e.g. 1080 px wide for Instagram, 1200 × 630 for link previews). For print, work from inches × DPI — a 4×6 photo at 300 DPI is 1200 × 1800 px.
Will resizing reduce the quality of my image?: Making an image smaller is essentially lossless visually — we use high-quality Lanczos resampling for crisp results, and each file keeps its original format. Enlarging beyond the original resolution can't add detail that isn't there, so upscaled images may look softer.
Can I resize several images at once?: Yes. Add as many images as you like and the same scale or pixel settings are applied to every one, then you download them together. To shrink file size rather than dimensions, use the Compress image tool instead.
