Hit an upload limit exactly

Job applications, government forms, school portals and visa sites often reject photos over 100KB or 200KB. Instead of guessing at a quality slider, pick the limit and Localvert finds the highest quality that still fits under it.

It first lowers the compression quality only. If the image still doesn't fit at the lowest sensible quality, it then reduces the dimensions step by step, so you get the best-looking result that meets the limit.

JPG or WebP?

Choose JPG when the file is going to a form or a person — every system accepts it. Choose WebP when the image is going on a website: it looks the same at a noticeably smaller size.

Frequently asked questions

Will my photo be uploaded?

No. Compression runs in your browser using its built-in image engine. Your photo never leaves your device.

Why is my compressed file not exactly the target size?

Compression works in steps, so the result lands at or just under your limit rather than exactly on it. Being slightly smaller is what upload forms want.

Can I compress iPhone HEIC photos?

Yes. HEIC photos are decoded in the browser and saved as JPG or WebP at the size you choose.
