How to Resize an Image
- Upload a JPG, PNG, or WebP image.
- Type a new width or height in pixels — the other dimension follows automatically when aspect ratio is locked.
- Or use a percentage button to scale relative to the original.
- Pick a format and click Resize & Download.
Pixel vs. Percentage Resizing
Pixel resizing sets exact dimensions — useful when you need a specific size (e.g. 1920×1080 for a wallpaper, 1080×1080 for an Instagram square).
Percentage resizing scales relative to the current size — useful when you want to make an image roughly half the size without caring about exact pixels.
About Quality on Downscale and Upscale
Downscaling (making an image smaller) uses high-quality resampling and gives clean, sharp output. Upscaling (making an image larger than the original) cannot recover detail that wasn't there — the pixels are interpolated, so the result looks softer than a true high-resolution photo.
Resize Image — FAQ
Does resizing reduce file size?
Smaller dimensions almost always produce a smaller file. JPG and WebP also let you tune quality on export to reduce file size further.
Will my image stay sharp after resizing?
Downscaling uses high-quality resampling (Pica when available, native canvas otherwise). Results are sharp for typical photo content. Upscaling beyond the original size is interpolation and will look softer.
Can I keep transparency?
Yes — export as PNG or WebP to preserve transparency. Exporting as JPG fills transparent areas with white.
What's the maximum size?
The output is capped at 8192×8192. The input upload is capped at 25 MB and 4096 px on the longest side.
