About The Image Resizer
Resize images to exact pixel dimensions or scale them by percentage, directly in your browser. This free online image resizer is perfect for preparing photos for profiles, banners, thumbnails, and platform‑specific dimensions — with no upload, no account, and fully private processing.
Why this tool is useful
- Fit images to exact platform dimensions (avatars, banners, thumbnails).
- Batch‑downscale photos to save storage space.
- Private — images are processed locally and never uploaded.
How it works (client-side)
- Drop or pick an image.
- Set a target width/height or choose a scale percentage.
- The browser resamples the image using high‑quality canvas rendering; download the resized result instantly.
Will resizing reduce quality?
Downscaling uses the browser’s high‑quality resampling, so images remain sharp. Upscaling will soften the image as expected, since new pixels must be generated.
Can I lock the aspect ratio?
Yes — width and height stay proportional by default. You can unlock them for free resizing when you need custom dimensions.
Is my image uploaded?
No. Resizing happens entirely in your browser using the Canvas API. Your image never leaves your device.
