Resize images online
Shrink or enlarge pictures to exact pixel dimensions right in your browser — in batches, keeping proportions. Files never leave your device.
How to resize a photo
- Drag your images into the box — the first file's dimensions fill the fields automatically.
- Enter the width or height you need (the other side follows the aspect ratio) or press 50% / 25%.
- Press Resize and download the result; the format stays the same as the source.
Limitations
Downscaling is always clean: the image is resampled in several passes, so it stays smooth with no jagged edges. Upscaling is allowed but adds no sharpness — pixels are simply stretched, the photo will not get crisper than the original. EXIF rotation of phone photos is applied automatically. iPhone HEIC is accepted via a dedicated decoder.

Frequently asked questions
How do I resize several photos at once?
Drop all files together: the width and height apply to each one. If they have different proportions, the Keep aspect ratio checkbox protects them from distortion.
What size do I need for an avatar or a cover?
Every platform has its own numbers, but 1080 px on the long side is almost always enough for covers and 400–800 px for avatars. Type the width — the height follows.
Can I enlarge a small image?
You can, but it will not get sharper: enlarging stretches the existing pixels. For print or a large screen, look for a bigger original.
Is the photo uploaded to a server?
No — processing runs in your browser, the file stays with you.
