Image Resizer
Resize JPG, PNG, or WebP images to exact dimensions or a percentage - with optional format conversion.
Whether you're fitting a photo into a specific upload slot, hitting a marketplace's dimension requirement, or just shrinking a huge camera file, this tool resizes JPG, PNG, or WebP images to exact pixel dimensions or a percentage scale, with an option to convert format at the same time. Resizing down preserves visual quality since you're discarding detail rather than inventing it; enlarging is limited by the same math, so use the AI Image Upscaler if you need to go bigger without softening.

Common questions
Does resizing lose quality?
Making an image smaller preserves visual quality. Enlarging beyond the original size will blur - use our AI Upscaler for that.
Can I keep the aspect ratio?
Yes - the lock icon keeps width and height proportional as you type.
Can I resize and convert format in one step?
Yes - pick a different output format alongside the new dimensions, and both changes apply together.
Does it upload my image?
No - resizing runs locally on a canvas in your browser.
