Resize by percentage or exact size
Scale images to a percentage of their original size, or enter a width and/or height in pixels. With the aspect-ratio lock on, the image fits within the size you enter without being stretched.
High-quality resampling
Images are resampled with your browser’s high-quality smoothing, then saved with the same professional encoders used by our compressors. You can also change the output format and quality in the same step.
Common sizes
Popular targets include:
- 1920 px wide for full-screen website images

- 800 px wide for email attachments and online forms

Frequently asked questions
Can I make an image bigger?
Yes, up to 200% with the percentage slider, or by entering larger pixel dimensions (up to 16,384 pixels per side). Enlarging cannot add real detail, and larger dimensions usually mean larger files.
Will resizing change the format?
No, the original format is kept by default. You can choose JPEG, PNG or WebP output in the settings.
