Attach files, voice or video to a comment

Updated Oct 11, 2026

Attach files, voice or video to a comment ​

Add a file, a voice note, or a video recording to a comment with the buttons in the comment box, then post it with Comment. Voice notes get a waveform player and a transcript. revis.io's UI also calls comments "notes".

Before you start

  • Who: Owners, Admins, Members, Project Admins, and Contributors, on any comment. Reviewers, on comments they wrote. Viewers can't. Guests can when the share link allows Annotate.
  • Where: the web app.
  • You need: a comment box on an item. Files need your organization to allow file attachments on comments; voice notes and video recordings always work. Voice needs a microphone, and video needs a browser that can record the screen.

Attach a file ​

  1. Select Add attachment (the paperclip) in the comment box.
  2. Choose one or more files.
  3. Type your comment and select Comment.

You can also drag files onto the comment box, or paste an image into it with ⌘V (Ctrl+V on Windows and Linux). A pasted image is named screenshot- plus a number. To add a file to a posted comment, point to it, select More, and choose Add Attachment, or drop the file onto it.

With no text box selected, ⌘V on a copied image or video opens Paste media. Choose Attach to comment or Add playlist item.

Record a voice note ​

  1. Select the microphone (Add audio note) in the comment box. Allow the microphone when your browser asks.
  2. Speak, then select Stop recording.
  3. Type a comment if you like, and select Comment.

Select the X (Cancel recording) to throw the recording away. Recording stops by itself at 10 minutes.

A posted voice note shows a waveform with a speed button for 1x, 1.5x, and 2x. Its transcript reads Transcribing… first, then the text. Select the text to expand it. If transcription fails, it reads Transcript unavailable. Audio files you attach get the same player.

Record a video comment ​

  1. Select Record video comment. The first time, choose your settings and select Start recording.
  2. Choose what to share in your browser's picker.
  3. Talk after the three-second countdown, then select Stop recording.
  4. In Review your recording, select Attach to comment. revis.io posts the comment with the recording.

To change Include camera, Camera, Bubble size, or Microphone, select the arrow next to the button (Change camera / mic). Videos stop at 10 minutes. Re-record and Discard in the review let you start over.

Reply with audio or video ​

  1. Point to a comment and select Reply with audio or Reply with video.
  2. Record as above. Post a voice note with Reply, or a video with Attach to comment.

If a comment doesn't save ​

A comment with a recording, and any reply, stays in the thread as Not saved with Retry and Discard. Select Retry to send it again. revis.io keeps the recording only in the open tab, so reloading the page loses it.

If a file fails after the comment posts, revis.io shows Failed to upload and the file's name, and the comment stays without the file.

Limits ​

  • Images: 150 MB. JPG, PNG, GIF, WEBP, BMP, TIFF, and PSD. SVG and HEIC aren't supported, even though the file picker may list them.
  • Video: 300 MB. MP4, MOV, WEBM, AVI, MKV, and M4V.
  • Audio: 50 MB. MP3, WAV, FLAC, AAC, M4A, and OGG.
  • PDF: 50 MB.
  • Through Add Attachment or a drop onto a comment, video can run 3 minutes and audio 10 minutes.
  • Organization Owners and Admins turn file attachments off under Organization settings > Uploads with Allow file attachments on comments.

WARNING

Every member sees Delete on an attachment, but only the comment's author and Owners, Admins, and Project Admins can delete it. For anyone else, revis.io hides the file until you reload the page, and the file stays.
