Reels / TikTok / Shorts Resizer
Frame your video with a move-only, locked 9:16 crop and a generic safe-zone overlay. Treat the guide as conservative framing help and verify the export in the destination app.
Generic 9:16 guidance
Hatched overlays conservatively mark top, bottom, and right-side regions where destination-app interface elements may cover content. They are not calibrated guarantees; verify in the destination app.
Vertical export target
The default target is 1080×1920. Depending on browser encoder support, the output can be H.264/MP4 or VP9/WebM; bitrate and destination acceptance vary.
Drag to reframe
Slide the locked 9:16 window across your footage to choose what stays in frame.
How to resize a video for Reels, TikTok & Shorts

- Export and download Review the exported result from Reels / Shorts Resizer, then download it.
Frequently asked questions
Are the safe zones exact?
No. The overlay is generic 9:16 framing guidance, not a measurement of a specific app version. Destination layouts vary by app, account, and device, so verify the export in the destination app.
Can I export 720×1280 instead?
Yes, switch the output preset in the right rail.
Is audio kept?
When compatible passthrough is available, the source audio track is copied without audio re-encoding. Check the export for your input.
Which platforms do the safe zones cover?
The same generic guide can help frame 9:16 exports for Reels, TikTok, or Shorts, but it is not platform-calibrated. Verify placement in the destination app.
What resolution does it export?
1080×1920 by default, or 720×1280 if you switch the preset. These are common 9:16 export sizes; destination requirements and codec acceptance vary.
How to verify a Reels / Shorts Resizer export
Treat the page preview and the downloaded file as separate evidence. Use a representative clip, keep the untouched source, and record the result that the task actually requires before changing any control.
- Before processing, note the source container, video and audio codecs when known, duration, dimensions, frame rate, orientation, audio-track count, and intended destination. Also record the exact cut, crop, timing, visual correction, or extraction you expect. These observations create a baseline for comparing the export instead of relying on memory.
- Run a short representative sample first and change one setting at a time. Browser codec support, available memory, hardware acceleration, and input structure can affect which processing path is available. A successful preview for one sample shows only that observed case; it does not establish compatibility for every file with the same extension.
- Inspect the preview around the portions most likely to expose defects: the beginning and final frame, cut boundaries, rapid motion, fine text, faces, object edges, gradients, orientation changes, and any section where sound should align with a visible event. For model-assisted tools, look for missed regions, unstable masks, invented detail, or frame-to-frame drift.
- Open the downloaded file in a separate current player rather than reviewing only the in-page preview. Confirm that it starts and ends where expected, plays through without an unexpected stall, and has the intended duration, dimensions, orientation, frame rate, audio presence, and synchronization. Check the file again in the platform or editor that will consume it.
- Compare the exported clip with the untouched source at the same viewing scale and, when useful, matched playback volume. Look for unexpected crops, padding, stretch, softness, banding, halos, color shifts, temporal jumps, repeated or missing frames, and changes in file size or codec that matter to the destination. Decide whether any difference is acceptable for the stated task.
- If the result is missing, fails to play, or differs from the preview, first confirm that the source opens independently. Reload the page, retry with a small controlled sample, reset optional controls, and preserve the exact on-page message. Testing one controlled change at a time makes browser, input, setting, and destination failures distinguishable.
- Record the Reels / Shorts Resizer URL, relevant settings, browser and device, date, source identity, output filename, and observed checks. Keep before-and-after files when the result matters. This record supports a reproducible comparison later and avoids treating a changed input, capability, or destination requirement as the same run.
