How to use

Pixels

Enter width or height and the other side follows the aspect ratio. Turn off "Lock ratio" to set both.

Percent

10–400% of the original. 50% halves both sides.

Output and quality

JPG, PNG or WebP, quality 50–100. Each result shows its size and weight.

Batch

Upload several files to process them with the same settings and download with "Save all".

FAQ

How do I reduce file size?

Resize the width to 1200–1600px and save as JPG at quality ~80; most photos end up under 500KB. WebP is smaller for the web.

Does enlarging lose quality?

Yes — upscaling beyond the original blurs. Use the largest original you have.

Instagram or YouTube sizes?

Use the Social Image Resizer presets.
