## About

Gmail, Outlook, Discord, WhatsApp, social platforms, cloud drives, government portals — the caps that reject your files, the real-file headroom after encoding, and a local tool for each one. Verified October 2026.

## Quick answer

What are the upload limits in 2026? The ones people hit most: Gmail 25 MB (≈18 MB real file), Outlook/Exchange ~35 MB, Discord 10 MB free, WhatsApp 64–100 MB video / 2 GB documents, Instagram 8 MB, Reddit 20 MB, portals 240 KB–2 MB. The rule that explains most rejections: email inflates files by ×1.35 (base64), and every "too large" is solvable locally — see the tool column.

## Notes

Verified October 2026 against each service's published documentation where available; limits change — check the service before blaming your file. Every tool linked above runs locally in your browser: your documents are never uploaded to a server, ours or anyone's.

## FAQ

**What is Gmail's attachment size limit?**

25 MB total per message on personal accounts — measured after base64 encoding, which inflates files by about 35%. The practical ceiling is roughly 18 MB of actual file. Workspace Enterprise Plus accounts can send 50 MB since February 2026.

**What is WhatsApp's video size limit?**

As of 2026 WhatsApp lists 64 MB on slower connections and 100 MB on faster ones for videos (status videos are shorter), plus up to 2 GB for documents. The bigger issue is re-compression — pre-compressing to 720p avoids it, which our WhatsApp guide covers.

**Why is my file rejected when it's under the limit?**

Email attachments travel base64-encoded (about 35% bigger on the wire), so a 20 MB file becomes ~27 MB and blows a 25 MB limit. Multiply by 1.35 before comparing, or compress the file first.

**How do I make a file smaller for a specific limit?**

Use the target-size tools: images compress to exact KB targets (20 KB–5 MB), PDFs shrink with the PDF compressor, and videos re-encode to your chosen size — all locally, nothing uploaded.
