Open toolWhy resize your images?
Oversized photos slow down websites, get rejected by upload forms and take forever to email. Resizing fixes all of that. You can shrink an image to an exact file size (like 20KB or 100KB), to exact pixel dimensions (like 800×600), or by a percentage of the original.
Which resize tool should I use?
If a form or portal tells you a file size limit in KB, use a resize-to-KB tool. If you need a specific width and height (like a social media cover), use the pixels tool. If you just want the image smaller overall, resize by percentage.

Frequently Asked Questions
What is the best way to resize an image?
It depends on the goal. For file-size limits, use a resize-to-KB tool. For exact dimensions, use the pixels tool. For quick shrinking, percentage resize is easiest.
Does resizing reduce quality?
Shrinking an image normally looks fine because pixels are merged smoothly. Extreme size reductions can soften details, which is expected and usually fine for web use.
Are these resize tools really free?
Yes — all FastResize tools are free forever, with no watermarks, no limits and no signup.
Do I need to install anything?
No. Everything runs in your web browser using HTML5. Works on Windows, Mac, Android and iPhone.
