How to use it
- Add your images.
- Pick pixels or percent and enter width or height, or choose a preset.
- Set quality for lossy formats.
- Compare and download.
What it keeps
- Proportions with the lock on.
- Image format, unless you change it.
- Transparency in PNG, WebP and AVIF.
What it removes or changes
- Pixels are resampled, so detail is lost when shrinking.
- Lossy formats are re-encoded, adding a generation of loss.
- Metadata is kept only if you choose.
Limits
- No enlargement by default, since it would add pixels but no detail.
- Resizing does not crop. Use Crop and rotate image for that.
- For HEIC photos use Resize HEIC.
Compatibility
The output is a standard JPG, PNG, WebP or AVIF, so it opens in the same places as the original format. For web pages, resize to the largest size the layout shows, not the original camera size.
Privacy
Resizing runs in your browser tab. Your images are not uploaded, and they are released when you close the page.
Resize before you compress
For most uses, lowering the dimensions saves more space than lowering quality, with a smaller visible cost. Resize to the size you actually need, then adjust quality if the file is still too large. Going the other way around often leaves you with a blurry image at a large size.
Troubleshooting
The image will not get bigger.
Enlargement is off. Turn it on if you accept a softer result.
The proportions changed.
The lock was off. Turn it on, or enter only one dimension.
The file is still big.
Reduce dimensions more, or lower quality.
