Common questions
Why compress to 300 KB?+
300 KB is a frequent upload cap on forms, portals and content systems — small enough to load quickly while keeping a photo looking good. This lands you under it in one click.
Is my image uploaded anywhere?+
No. This runs entirely in your browser using your device's own processor — your image never leaves your computer or phone.
What if it can't reach 300 KB?+
For very large images we gently reduce the dimensions too. If it still can't fit while staying usable, we give you the smallest version and tell you — never a broken file.
Which formats work?+
JPG, PNG and WebP. The result is a JPG (or WebP) since those compress to a precise size.
Is there a limit or watermark?+
No watermark, no signup, free — and since it's all in your browser, no upload size limits either.
