Too many files for one email or upload? Choose them and split them into parts that stay under a size limit, such as 25 MB, or into groups of a fixed number of files.
Your files never leave your device
Many email services accept about 20–25 MB per message, and many web forms limit uploads too. Set the limit and every batch stays under it, so you can send the files in several messages without guessing.
The batch ZIPs store the files without recompressing them, so a ZIP is about as large as its files and the size shown is accurate. You can also download all batches as subfolders in one ZIP or, in Chrome and Edge, save them straight into a folder.
25 MB works for most providers; use 20 MB to be safe. Attachments get bigger when sent, so a little margin helps.
Usually not much: photos, videos and PDFs are already compressed. The tool stores files as they are, so the ZIP size is predictable.
It gets its own batch and a warning, because one file cannot be split by this tool.
Yes. Turn on “Keep subfolders inside each batch”.
No. The batches are made in your browser on your device.
Use the button on each batch, or download all of them at once as folders in one ZIP.
