How to Resize an Image Without Losing Quality
Updated June 2026
Resize images by pixels or percent.
Whether it's for a website, an upload limit, or a profile picture, resizing an image is quick — and you can do it free without installing anything or uploading your photo.
How to resize
- Open the image resizer below and choose your image.
- Enter a new width (height adjusts automatically to keep the proportions).
- Or scale by a percentage, then download.
Why "keep aspect ratio" matters
If you change width and height independently, the image stretches and looks squashed. Locking the aspect ratio keeps it looking natural — change one dimension and the other follows.
Shrinking vs enlarging
Making an image smaller keeps it crisp — you're throwing away extra pixels. Making it bigger than the original forces the software to invent pixels, which looks soft or blocky. For best quality, start from the largest version you have.
Privacy tip
Some resizers upload your photo to a server. A browser-based tool (like the one below) does it on your device, so personal photos never leave your computer or phone.

Frequently asked questions
What's the best format to save in?
Use JPG for photos (smaller files), PNG when you need transparency or sharp text, and WebP for the best size-to-quality balance on the web.
Can I make a small image bigger and keep it sharp?
Only so much — enlarging always loses some sharpness because the detail isn't in the original pixels.
