How to Compress Video for Email Attachment

Reduce video file size to fit email attachment limits. Browser-based compression — no upload to any server.

Most email providers limit attachments to 25 MB, but video files are often much larger. Compressing video before sending is essential for email delivery.

ConvertCraft's Video Compressor uses browser-based FFmpeg to reduce file size while maintaining acceptable quality. Your video never leaves your device.

Open the Video Compressor, select your video, choose a target file size or quality preset, and click Compress. The tool shows a size estimate before processing.

For best results with email, target 720p resolution and medium quality. This typically reduces a 1-minute 1080p video from ~150 MB to under 20 MB.

Ondersteunde invoerformaten omvatten MP4, MOV, AVI, MKV en WebM. De uitvoer is altijd MP4 (H.264) voor maximale compatibiliteit met e-mailclients en apparaten.

Frequently Asked Questions

Wat is de maximale bestandsgrootte van een e-mailbericht?

Gmail stelt 25 MB op, Outlook stelt 20 MB en Yahoo Mail 25 MB op. Voor grotere bestanden, overweeg om een cloud-deling link te gebruiken in plaats van het direct te comprimeren.

Hoeveel video kan worden gecomprimeerd zonder merkbare kwaliteitsverlies?

Een typische 1080p video kan worden gecomprimeerd door 60-80% met minimale zichtbare kwaliteitsverlies wanneer je de medium kwaliteit instelling gebruikt.

Waarom kan ik niet naar een exacte bestandsgrootte comprimeren?

Video compressie is content-afhankelijk – scènes met beweging comprimeren anders dan statische scènes. Het hulpmiddel schat de uitvoergrootte, wat enigszins kan variëren.
