Because the encoded message has to fit, not just the file, it is worth typing 18 rather than 25 and letting Bindery find the boundary. Everything happens locally: the PDF is opened and written in your browser, and nothing is transmitted to Bindery or anyone else. If the file is over 200 MB, big-file mode streams it and offers page-count splits instead of size-based ones. And if you would rather send one file, compress first and check the sizes on the cards; Balanced often brings a 31 MB scan well under the cap without a visible change.
How it works
- Drop the PDF and open Split; pick “under a size” and enter your limit
- Preview which pages fall into each part on the board
- Split and download the ZIP; attach the parts to separate emails
Questions people ask
Should I split or compress a 30 MB PDF for Gmail?
Try Compress first: it computes the real size of three levels before you commit, and Balanced usually brings image-heavy files far under 25 MB with no visible change. Split when the content must stay byte-for-byte identical, or when even Email & web is still too large.
What does the recipient receive?
Ordinary PDFs, each a consecutive range of the original pages, named after the source with a part number. They open in any viewer without special software, and merging them in order — in Bindery or elsewhere — rebuilds the original document.
Does the split need an account or a Pro plan?
No. Split, including the size-based mode, is part of the free tier: ten completed jobs per UTC day, no file-size cap of Bindery’s own, no sign-in. Pro adds unlimited jobs and synced recipes but no extra capability here. A split into several parts counts as one job.
