Image Compressor FAQ

Will I lose image quality after compression?
We use smart compression algorithms. Standard settings (70%-80% quality) can reduce file size by 50% to 80% with virtually no visible difference to the naked eye. PNG compression is lossless by default if quality parameters are not modified.
Is there a limit on the number or size of images I can compress?
No hard limits are enforced. However, since all file resizing and compression happen in your local browser's memory, device performance may vary. For optimal results, we suggest processing batches of up to 100 images at a time.
How does the 'Save to Directory' feature work?
In modern browsers like Chrome or Edge, you can authorize the tool to connect to a local directory. Compressed files will then write directly to your computer without prompt dialogs, streamlining large batch processing.
