Frequently asked questions
How do I compress an image to 100 KB?
Upload your image above. The target is preset to 100 KB, so just click Compress — iResize searches for the highest quality that keeps the file under 100 KB, then you download it.
Is it free and private?
Yes — completely free with no watermark or sign-up, and your image is processed entirely in your browser, so it never gets uploaded.
What if it can't reach 100 KB?
Compression aims for at or just under 100 KB. For very small targets on large, detailed photos, also turn on Resize to shrink the dimensions — that easily gets you under the limit.
