Frequently asked questions
- Does compression lose quality?
- The lossless level recompresses nothing: it only restructures the file. The light, balanced and maximum levels rebuild pages as images, so sharpness drops in proportion to the savings.
- How much weight will I save?
- It depends on the document. ARVIO shows the original and final size so you can retry with another level if you're not happy.
- Is my file uploaded to a server?
- No. This tool runs entirely in your browser.
