About this image resizer
Need an image at exactly 800×600 for a form, a profile, a marketplace listing? Upload it, type the pixel size you need, and download the resized file — the conversion happens on your device, so even personal photos stay private.
How to use it
- Choose an image — its original size appears.
- Type the new width (height follows if the ratio lock is on).
- Pick a format and click Resize to get the download.
Worked example
A 4000×3000 phone photo resized to width 800 becomes 800×600 with the ratio locked — and usually drops from megabytes to a few hundred KB as JPG.
Frequently asked questions
Does resizing reduce quality?
Shrinking is usually invisible. Enlarging beyond the original size cannot add detail and may look soft — the tool allows it, your eyes decide.
Which format should I choose?
JPG for photos and smallest files, PNG for graphics/text and transparency, WebP for the web (small and modern, but not accepted everywhere).
Are my images uploaded?
No — everything runs locally in your browser.
