Image Resizer
Set an exact width and height, or scale by percentage. Keep the shape locked so nothing stretches, or unlock it for an exact size.

Two ways to resize
- By pixels - type the width or height you need. With the aspect-ratio lock on, the other side follows automatically.
- By percent - scale from 1% to 200% of the current size.
Common sizes
- Instagram post - 1080 x 1080 (square) or 1080 x 1350 (portrait)
- Full HD / YouTube thumbnail - 1920 x 1080 / 1280 x 720
- Website hero image - around 1920 pixels wide
- Email - 600 to 800 pixels wide
If the target shape differs from your photo's, crop first so nothing is squashed.
Making images larger
Resizing up to 200% is fine for small changes. For big enlargements, the upscaler goes to 8K and has an AI option that rebuilds detail.
Frequently asked questions
Is the image resizer free?
Yes, and it needs no account.
Will resizing reduce quality?
Making an image smaller keeps it sharp. Enlarging spreads the same detail over more pixels, so large enlargements look soft - use the upscaler for those.
How do I avoid stretching?
Keep the aspect-ratio lock on, or crop to the target shape before resizing.
Can I resize many images at once?
Yes. Batch resizes up to 20 images to the same size.
