What is the Image Compressor?
An image compressor reduces file size by re-encoding images at an optimised quality and, optionally, a smaller maximum width/height. AnyShift shows before/after sizes for every file, can keep the original format or switch to WebP/AVIF for bigger savings, and never returns a file larger than the original.
Images are converted inside your browser — nothing is uploaded, so it works for private photos and client work.
How to use the Image Compressor
- Drop images (JPG, PNG, WebP, AVIF, HEIC).

Frequently asked questions
How much can I compress without visible loss?
JPG/WebP at 75–85% quality usually looks identical to the original while being 40–70% smaller. Resizing a 4000-px photo to 2000 px cuts size by about 75% more.
How do I compress an image to 100 KB or 1 MB?
Lower the quality and set a max width (e.g. 1600 px). WebP gets smallest files at the same quality.
Are PNG screenshots compressed?
Yes. For maximum savings, convert screenshots to WebP; PNG stays lossless.
