Use Imagera to compress video in your browser when a recording is too large to share. This free video compressor helps you reduce video file size for email, chat or a presentation on a compatible phone or computer. Add a MP4, MOV, WebM or MKV file, choose a quality or size goal, and check the result. The video is processed on your device without uploading it. 2 free downloads, 8 more after sign-in.
Published · Updated · by the Imagera teamImagera is a browser-based AI studio for images, video, music and voice, so you do not need a separate app and account for every model. Pricing is credit-based: one balance covers every tool, and each job shows its credit price or estimate before you run it.







A 100 MB recording reduced to 25 MB saves 75% of its file size. That percentage measures storage saved, not picture quality.
At a combined bitrate of 1 megabit per second, 60 seconds uses about 7.5 megabytes before file overhead. Twice the duration needs twice the data at that rate.
Halving both frame dimensions leaves one quarter of the pixels. Compression can reduce dimensions; the Video Enhancer is the separate tool for enlarging footage.
Try 4K Video EnhancerThe size planner reserves 6% of a target for overhead and encoding variation. It is still an estimate, so check the finished file before sending it.
Start with Balanced when you want to reduce a recording without choosing a size limit. The Quality choices are Smallest file, Balanced, High quality or Target size. A preset controls how much data the picture receives; a size goal works backward from the length of the recording.
The Resolution choices are Original, Up to 1080p, Up to 720p or Up to 480p. Reducing the picture dimensions can help when you need a lighter file. Portrait clips stay portrait, and the compressor never enlarges the picture.
For Discord, WhatsApp or email, check the limit shown where you plan to send the file. Choose the size-based quality mode and enter a Target size below that limit. Leave room for other attachments and check the completed file rather than assuming the estimate will fit.
A long clip has to spread the same space across more seconds. With Resolution left at Original, the size planner may lower the dimensions to fit the available picture data. If the goal is too small, it reports a minimum estimate. Raise the goal, remove unneeded sound or use the Video Trimmer before trying again.
Re-encoding trades picture detail for less data. A smaller file can still look useful, but this tool does not offer lossless picture compression. Check motion, faces and small lettering in the result before using it. Keep the original recording for later edits.
If a screen recording becomes hard to read, allow a larger file or reduce its length instead of forcing a tighter target. Compression cannot repair an already blurry source. The separate Video Enhancer can upscale and process soft footage; it does not make this compression pass reversible.
Leave Sound enabled when the recording needs its voice or music. Compatible sound can pass through unchanged; other sound may need conversion. If the browser cannot preserve the audio track, the result reports that it could not keep it. Play the result before sharing a spoken explanation.
Turning Sound off removes the track. In size-based mode that leaves more of the budget for the picture. The browser also chooses an available output encoder, so the downloaded file may use a different format from the original.
The file picker accepts MP4, MOV, WebM or MKV. Its contents must also be readable by your browser, and the browser needs a working video encoder. If it cannot process the clip, try an up-to-date Chrome, Edge or Safari, or move the file to another device. A recognized file extension alone is not a guarantee.
The engine allows up to 15 minutes and 1 GB per run on phones, or 60 minutes and 4 GB on computers. Both limits apply. These are guardrails for a result assembled in memory, not a promise that every device will finish every file within them.
Your selected video is opened as a local file, decoded and re-encoded in the browser, then returned as a result on your device. The compression engine does not send the footage to a server. This is useful for a client recording or a personal clip you have not shared yet.
The compressor still fetches page code and can send error reports even though the footage stays local. There is no fixed completion time promised here: encoding depends on the recording and the capabilities available on your device.
Add a MP4, MOV, WebM or MKV video from your device. Keep the original for future editing.
Begin with Balanced, or choose the size-based mode and enter your limit. Adjust Resolution and Sound for the clip.
Start compression, then compare the Before and After sizes. Review the picture, the reported dimensions and the sound before sharing.

Yes. The compressor reads your chosen file locally and creates the smaller result in your browser. Your footage is not uploaded for this processing.
Select the size-based mode under Quality, then set Target size to 10 MB. For a strict ceiling, choose a lower value and inspect the final file size; the encoder aims for a budget rather than an exact byte count.
Not without some picture loss in this tool: it re-encodes the frames. Start with Balanced, inspect the details you care about, and allow more data if they soften. Keep the source if you need its original quality later.
Use the upload limit Discord currently shows you as the ceiling, then set a smaller size goal here. Check the exported file before attaching it. If a long clip looks too rough, shorten it first or allow a larger file where your destination permits.
Choose a target below the attachment limit for your message, including any other files you are sending. Run compression and inspect the finished size. If the recording becomes unreadable at that size, send a shorter excerpt or use a file-sharing link.
Create a smaller copy here, using a size goal that fits the limit shown in WhatsApp. Review its picture and sound before sending. This tool controls the file it creates, not how a messaging service processes it afterward.
Yes, when the phone browser can decode the recording and encode a new video. Use a current browser and try a short clip first. If the file is unsupported, opening it on another device may help.
The phone limits are 1 GB and 15 minutes; the computer limits are 4 GB and 60 minutes. A 90-minute video exceeds the duration allowed even on a computer, regardless of the size goal. Both limits apply, and memory or codec support can still prevent a run. Use shorter excerpts for longer recordings.
The selected settings may leave little room to reduce an efficient source. If the new file is as large as the input or larger, the tool stops instead of offering it. Try a lower resolution or a more compact quality choice.
Choose MP4, MOV, WebM or MKV. Support also depends on the video encoding inside the file and what your browser can decode. The output format is chosen from the encoders available on that browser and may differ from the source.
Check that Sound was enabled and that the original had an audio track. The result reports whether sound was kept, removed or could not be preserved by this browser. If it could not be kept, retry the original in another compatible browser.
With Resolution at Original, the planner can reduce dimensions when the size budget cannot support the original picture. A longer recording leaves fewer bits for each second. Raising the target or trimming the clip gives the picture more room.
If you only need part of it, yes. Use the separate Video Trimmer first. A shorter duration leaves more data per second at the same file-size goal, which can make a tight limit less damaging to the picture.
This Free Studio workbench accepts one video per run. Finish one clip, then replace it with the next recording.
The compressor uses the displayed width and height and writes phone rotation into the picture. Resolution caps follow the shorter side, so a portrait recording keeps its orientation rather than becoming landscape.
The smaller output cannot recreate discarded information. Keep your source recording for that. Imagera’s separate Video Enhancer offers enhancement and upscaling, but its processed result is not a recovery of the exact original.
Only if you still need a smaller copy and can accept another loss of detail. When testing different settings, start each attempt from the original recording rather than the previous export. That avoids stacking compression passes.
