How to compress an image to 300 KB

  1. Drop your JPG, PNG, WebP or HEIC image into the box above, or click to choose it.
  2. The target is already set to 300 KB. Change it if your form needs a different limit.
  3. Wait a second while the image is optimised, then click Download.

Why 300 KB?

Many websites cap uploads at 300 KB, especially for product photos and marketplace listings. A typical phone photo is 2–5 MB, so it gets rejected. This tool keeps the best possible quality while guaranteeing the file fits the limit.

Frequently asked questions

How do I reduce a photo to 300 KB?

Drop your image into the tool above. It automatically finds the highest quality that fits under 300 KB, and only shrinks the dimensions if quality alone is not enough. Then click Download.

Are my images uploaded to a server?

No. FileCrafty compresses images entirely inside your browser using your own device. Your files are never sent anywhere, which also makes it fast.

Will the image still look good at 300 KB?

Usually yes — 300 KB is enough for a sharp photo at typical screen sizes. The tool always keeps as much quality as the size allows.

Can I compress iPhone HEIC photos?

Yes. HEIC photos are converted and compressed in one step, so you get a JPG or WebP that any website accepts.

Should I choose JPG or WebP?

Choose JPG if a form or website asks for it — it works everywhere. WebP gives smaller files at the same quality and keeps transparency, but some older forms do not accept it.
