Frequently Asked Questions
How many images can I compress in one batch?
There’s no fixed count limit in the tool itself, though very large batches naturally take longer and use more of your upload bandwidth at once.
How do I download all the compressed images?
Once processing finishes, every compressed image is bundled together into a single ZIP file for one-click download.
Can I mix different image formats in one batch?
Yes — JPG, PNG, WebP and AVIF files can all be uploaded together; each one keeps its own original format after compression.
Is the same quality setting applied to every image in the batch?
Yes — one quality slider value applies to the whole batch; there’s no per-image setting.
Does this happen in my browser or on a server?
Processing happens on the server in memory for your request, then every file is discarded — nothing runs locally in your browser and nothing is kept afterward.
Will filenames change after bulk compression?
No — each file keeps its original name inside the ZIP, just with the new compressed file size.
