Choose what happens when proportions differ.
Crop to fill
Makes the exact target size by cropping the edges from the centre when needed.
Pad to fit
Keeps the whole image and adds space around it to reach the exact target size.
Resize dimensions. Compress file size. They are not the same job.
Resizing changes pixels and canvas dimensions. Compression is for making a file lighter without necessarily changing its dimensions. Image Compressor is the next planned image tool.
Nothing to upload. Nothing to delete.
Your image files are processed on this device and are not uploaded to ToolkitLoop. Resized exports are created without original metadata where supported by the browser processing pipeline.
Image Resizer FAQ
Is Image Resizer free?
Yes. You can resize JPG, PNG and WebP images without an account.
Are my images uploaded?
No. Image processing runs locally in your browser. Your image files are not uploaded to ToolkitLoop.
Can I resize multiple images at once?
Yes. Add up to 10 images and apply the same settings with a sequential, browser-local queue.
How do I resize without stretching?
Use Fit to keep the full image, Crop to fill for an exact size, or Pad to fit to preserve the whole image inside an exact canvas.
Why can an enlarged image look blurry?
Standard resizing changes pixels but does not invent new image detail. Turning off the no-enlarge setting may make a small image look softer.
Does resizing always make files smaller?
No. File size also depends on format, quality and image content. Use Image Compressor when your goal is a smaller file.
