How to resize an image

Upload your image (JPG, PNG, WebP, or HEIC).
Pick a mode: exact dimensions, percentage scale, or target file size in KB.
Download the resized image. Your upload is deleted from our server automatically.

Why use Forge Files?

Target-KB mode: made for government portals, job applications, and exam forms that reject photos over a size limit.
Visual cropper included: drag handles to crop exactly what you need before or after resizing.
Verifiably private: images are deleted after download: the code is open source so you can check, or self-host.

Three ways to resize

Resize an image by exact width/height in pixels, by percentage to scale it up or down, or to a target file size in KB when a form caps the upload. That last mode is the one people hunt for: set "under 200 KB" and get a file that fits. You can also crop visually in the same tool.

Resize vs. compress vs. crop

Resize: change dimensions (or hit a KB target).
Compress: keep dimensions, shrink file size.
Crop: trim to a region of the photo.

Is the Resize Image tool private?

Yes. Your file is uploaded over encrypted HTTPS, processed, handed back, and then deleted — the upload goes the moment the Resize Image operation finishes and the result the instant you download it, with an hourly sweeper as a backstop. Unlike closed tools that just claim they don't keep your files, Forge Files's code is fully open source, so you can verify exactly how the Resize Image tool handles your data — or self-host it. No account, no watermark, no upsell. See our privacy details for the full picture.
