About 500MB Video Compression
A 500MB cap covers many real-world limits: email services that allow large attachments, LMS and portal uploads, and platform requirements for longer clips. This tool re-encodes your video in the browser and iterates the bitrate until the result lands under 500MB while keeping the best achievable quality — roughly an hour of 720p or 20–30 minutes of 1080p. Nothing leaves your device.Before emailing a PDF, open the downloaded copy and check fine text at the intended viewing size. The tool can reduce image detail; its target size is not guaranteed. If forms, signatures or searchable text matter, keep the original PDF.

Frequently Asked Questions
How long can a 500MB video be?
About 50–60 minutes at 720p or 20–30 minutes at 1080p, depending on scene motion. The compressor automatically picks the highest bitrate that fits the budget.
Which platforms have a 500MB limit?
Many upload portals, learning management systems and mail services with large-attachment plans cap files around 500MB. Always confirm the exact limit of your target platform.
Will 500MB compression hurt quality?
For clips shorter than the durations above, barely — the tool only lowers bitrate as much as needed. Longer clips are re-encoded at the best bitrate that still fits.
Can I compress to a different cap like 1GB?
Yes. The target field accepts any value from 5MB to 2000MB, so you can aim at 1GB, 200MB or any platform limit.
Compress video
Re-encode with a lower bitrate or resolution. Check playback, sound and the final size; a strict target may need further adjustments.
There is no guaranteed saving or exact target for every file. If the result is larger, some tools return the original; compare its format and size before sharing. Before emailing a PDF, open the downloaded copy and check fine text at the intended viewing size. The tool can reduce image detail; its target size is not guaranteed. If forms, signatures or searchable text matter, keep the original PDF.
