Zip multiple files into one archive for email when attachments must travel together. Compression runs with JSZip in your browser — files are not uploaded to a zip website.
ToolsProcessed privately in your browser — files are not uploaded.
Zipping never sends file bytes to SortMyFile. The archive is built on-device.

JSZip builds the archive locally.
Send or store the single file.
Bundle assignment PDFs and images for a single email, or pack receipts before a reimbursement ticket.
Zip Files keeps inputs in your tab. That matters when you are drafting numbers, text, or codes you would rather not paste into an upload-based SaaS form. Zipping never sends file bytes to SortMyFile. The archive is built on-device. If a step needs a one-time language pack or WASM library from a CDN, that is asset delivery — not your document contents being sent to SortMyFile for server-side processing. Close the tab when you are done if you want memory cleared.
Pack multiple files into a ZIP archive. Before you run Zip Files, keep an original copy of every source file. Spot-check the download on the same device you will use for the portal or email. Large scans and phone photos are limited by browser RAM — if a run stalls, shrink the input first or split the job. SortMyFile browser tools stay free forever with no daily caps.
Bundle assignment PDFs and images for a single email, or pack receipts before a reimbursement ticket. People reach for Zip Files when a form, HR desk, or messaging app rejects the current file shape, size, or format and installing desktop software is overkill. Pair it with unzip-files, file-hash, merge-pdf when you need a short pipeline (for example compress then OCR, or HEIC to JPG then JPG to PDF). Results are not a substitute for official portal rules — always re-read the receiving site’s instructions before a deadline.
Zip Files trades convenience for honesty about browser limits. Extremely large files, corrupted inputs, or DRM-protected media can fail. Password-protected PDFs need a password you already know — SortMyFile does not crack encryption. Free use does not require an account; Pro (when checkout ships) is planned to raise limits and reduce ads. Until then, the free tier is enough for most one-off private jobs.
