How do I compress a video to under 8 MB?

In Wexporting, add the video, choose Target Size Mode, and enter 8 MB. Wexporting compresses the video to fit at or under 8 MB automatically — useful for Discord, email, and other upload limits — without manual bitrate math.

Can I compress an image to exactly 1 MB?

Yes. Wexporting's Target Size Mode lets you enter an exact size such as 1 MB, and lands the exported image at or under that limit across formats including WebP, AVIF, PNG, and JPG.

Do I need FFmpeg or the command line?

No. Wexporting is powered by the same FFmpeg encoders the pros use (VP9, AV1, libwebp) but does the target-size bitrate calculation and two-pass encoding for you, so there is no command line and no math.

Can I target several sizes at once?

Yes. Wexporting can hit several target sizes in a single pass — for example 1 MB, 2 MB, and 3 MB — and can combine this with batch processing across many files at once.

Compress a video or image to an exact file size

Wexporting compresses an image, video, or GIF to an exact size limit — under 8 MB for Discord, exactly 1 MB for an upload cap — in a few clicks. It is powered by FFmpeg but does the bitrate math and two-pass encoding for you, so there is no command line.

The hard way: raw FFmpeg

FFmpeg is the best media engine there is, but it cannot hit an exact file size on its own. To land a video at, say, 8 MB you have to compute the bitrate by hand, run a two-pass encode, and often repeat it when the result overshoots:

# 1. work out the bitrate by hand:
#    (target_MB * 8192) / duration_sec  -  audio_kbps
# 2. first pass
ffmpeg -y -i in.mp4 -c:v libx264 -b:v 1350k -pass 1 -an -f null /dev/null
# 3. second pass
ffmpeg -i in.mp4 -c:v libx264 -b:v 1350k -pass 2 -c:a aac -b:a 128k out.mp4
# 4. overshot 8 MB? recompute the bitrate and run it again.

The easy way: Wexporting

Wexporting runs those same FFmpeg encoders under the hood, but you just type the size you need. Add a file, choose Target Size Mode, enter 8 MB (or 1 MB, or whatever your limit is), and export. Wexporting handles the bitrate calculation and two-pass encoding automatically and processes everything locally on your PC, so your files never leave your device.

What people use it for

Compress a video to under 8 MB or 10 MB for Discord.
Shrink an attachment to fit an email or upload size cap.
Get an image to exactly 1 MB for a form or marketplace.
Produce web-optimized WebP, AVIF, WebM, and MP4 assets that load fast.

Several sizes in one pass

Wexporting can target multiple sizes at once — for example 1 MB, 2 MB, and 3 MB in a single pass — and combine this with batch processing to do it across many files. For the full feature breakdown, see how Target Size Mode works, and the supported formats.

Which file types support a target size?

Target sizing works across Wexporting's supported formats — images (AVIF, WebP, PNG, JPG), video (MP4), and animated loops (GIF, WebM) — all converted locally on your PC.
