Frequently asked questions about Image Compressor
Does it significantly reduce image quality?
At 70-80% quality, the difference is barely noticeable to the eye, while file size is significantly reduced.
Are files uploaded to a server?
No. All processing happens in your browser and files are never sent to any server.
How much can the file size actually be reduced?
A photo straight from a phone typically lands at 20-40 % of its original size at quality 80. Images that were already compressed, or flat graphics with few colours, have far less room, while detailed photographs shrink the most.
Can I compress several images at once?
Yes — select or drag in multiple files and they are processed one after another with the same quality setting. The results can be downloaded as a single ZIP, which is handy when you are preparing dozens of blog or product images.
What quality setting is best for website speed?
For in-article photos, quality 75-85 is the sweet spot where the file drops a lot without visible artefacts. For Core Web Vitals, getting the largest above-the-fold image under about 200 KB is what actually moves your LCP.

For web images, compressing at 70-80% quality reduces file size by 50%+ with no visible difference.
