Pixels vs percentage

Pixel resize sets an exact width and height — what Instagram, LinkedIn, and printers care about. Percentage resize scales relative to the original (50% of a 4000px photo is 2000px). Use pixels for platform requirements; use percent for a quick downscale before email.

Upscaling warning

Making a small image larger cannot invent real detail. Soft, blurry results are normal. Prefer shooting or exporting larger, then resize down.

Privacy

Resizing runs on your device. Files never leave your browser.

Frequently asked questions

How do I resize to 1080×1080 for Instagram?

Click the Instagram post preset, drop your image, download. Aspect lock keeps proportions when you edit one side.

Does resizing reduce quality?

Shrinking usually looks fine. Enlarging beyond the original resolution invents pixels and looks soft — avoid large upscales.

Passport photo size?

Use the 600×600 preset as a starting point, then check your country’s exact mm/px rules.

Batch resize?

Yes — drop multiple files and download a ZIP. Very large drops process about 50 at a time so phones/low-RAM tabs stay usable; drop again for the rest.

Is there a watermark?

No. PNG/JPG export only with your content.
