Resize Image

Resize any image to exact pixel dimensions — type your own width and height, or jump to a preset page for the platform you’re posting to. Free, no signup, and your image never leaves your device.

Free, no signup, no watermark. If a target can’t be reached, we tell you exactly why and what to change.

Resizing without the usual mistakes

Two things ruin most resized images: stretched proportions and accidental quality loss. This tool avoids both — platform presets crop to the exact target ratio from the center (no squashing), and the custom tool keeps your aspect ratio locked unless you choose otherwise. Output quality stays high and the before/after sizes are always shown.

If your real goal is a file-size limit rather than pixel dimensions, you want the compressor instead — or run both: resize to the stated pixels here, then compress to the stated KB.

Common dimension targets, for reference

Numbers that come up constantly: 1280×720 (YouTube thumbnail), 1080×1080 (Instagram post), 1080×1920 (stories and reels covers), 400×400 (profile avatars), 1584×396 (LinkedIn banner), 600×600 (US passport photo at 300 DPI), 200×230 (the photo field on many application portals), 140×60 (signature fields).

If your target is on that list, the preset pages above handle ratio and crop automatically. For anything else, the custom tool takes any width and height up to 8000px — with aspect ratio locked by default so nothing gets distorted.

Private by architecture, not by promise

Your files are processed entirely on your own device — they are never uploaded to us or anyone else. We couldn’t see them if we wanted to. This website is served from servers in the United States (North Carolina).

Processed on your device

The compression engine is JavaScript running in your browser. There is no upload step in the code — nothing to trust, just how it works.

No signup, no watermark

Every tool is free and works instantly. No account, no email required, no marks on your files.

Honest results

If your target size can’t be reached at acceptable quality, we say so and tell you exactly what to change — not silently degrade your file.

Frequently asked questions

Will resizing distort my image?

No. Preset pages crop centered to the exact target ratio, and the custom tool keeps your aspect ratio locked by default — enter just a width and the height follows automatically. Nothing gets stretched or squashed.

Can I enlarge a small image?

Yes, up to 8000px on the long side — but upscaling can’t invent detail, so expect softness when enlarging a lot. For meeting a KB file-size minimum specifically, the dedicated increase-size tool handles quality and encoding better.

Is the image uploaded during resizing?

No — like every KBWise tool, resizing runs entirely in your browser.

What happens to the parts cropped away by a preset?

Preset pages crop from the center to hit the exact target ratio, trimming the longer dimension evenly on both sides. Your original file stays untouched on your device — only the downloaded copy is cropped.
