Resize image
Resize images to exact dimensions without uploading files
Use resize when a site, marketplace, profile or document needs a specific image size. QuokkaPix keeps the operation local and lets you choose exact width, height, fit behavior and export format before processing one file or a batch.

How it works

3
Choose whether to preserve proportions or fit into the target box.
4
Export and check that the final dimensions match the destination.
Resize checks before export
A resized image should hit the requested pixel dimensions without stretching the subject or making important detail too small.
| Check | Why it matters | What to do |
|---|---|---|
| Exact pixel size | Upload forms and templates often reject files that miss the target dimensions. | Confirm width and height in the result details. |
| Aspect ratio | Changing width and height independently can stretch faces, products or logos. | Use fit/crop rules intentionally instead of forcing both sides blindly. |
| Upscaling | A small source can become larger but not truly sharper. | Avoid upscaling unless the destination requires the canvas size. |
| Sharpness after export | Resizing can soften small labels, UI screenshots and text-heavy images. | Open the downloaded file at final display size. |
FAQ
Are images uploaded to resize them?
No. Resizing runs locally in the browser.
Can I resize a batch?
Yes. Batch mode applies the same size rule to every selected file.
Will resizing improve a blurry image?
No. It changes dimensions; it does not recreate detail that is not present in the source.
