Any ratio. Any file.

Q: What is the difference between crop, blur fill, and solid fill?

Crop scales the file to cover the target frame and trims the edges — best when the subject is centred. Blur Fill scales to fit inside the frame and fills the empty bars with a blurred version of the image. Solid Fill adds classic black or white letterbox/pillarbox bars.

Q: What is the free tier limit?

The free tier allows 3 conversions per day. Output includes a watermark. Purchase a Creator or Studio licence to remove it and unlock unlimited conversions.

Q: Can I convert images and videos to the same target ratio in one batch?

Yes — Studio Batch mode accepts mixed queues of images and videos. All files are converted to the same target ratio, fill mode, and format in one pass.

Convert any image or video to any aspect ratio — 9:16, 16:9, 1:1 and beyond. Crop, blur fill, or solid bars. No Premiere. No command line.

FAQ

Common questions

What file formats does Aspect Perfect support?

Images: JPG, PNG, WEBP. Videos: MP4, MOV, AVI, MKV, WebM. If FFmpeg can open it, Aspect Perfect can convert it.

What is the difference between Crop, Blur Fill, and Solid Fill?

Crop scales the file to cover the target frame and trims the edges — best when the main subject is centred. Blur Fill scales to fit inside the frame and fills the empty bars with a softly blurred version of the image — looks natural on any platform. Solid Fill adds classic letterbox or pillarbox bars (your choice of black or white) — clean and professional.

Does it need an internet connection?

Only to validate your licence key on first launch (and occasionally after). All conversion processing is 100% local — your files never leave your machine.

What is the free tier limit?

The free tier allows 3 conversions per day. Output files include a watermark. Purchase a Creator or Studio licence to remove it and unlock unlimited conversions.

Is FFmpeg included or do I need to install it?

FFmpeg is bundled inside the Aspect Perfect installer. You don't need to install anything else — no Homebrew, no terminal commands.

Can I convert images and videos together in one batch?

Yes — Studio Batch mode accepts a mixed queue of images and videos. All files are converted to the same target ratio, fill mode, and output format in one pass. Output filenames follow the pattern filename_16x9.mp4.

What is Batch mode and who is it for?

Batch mode (Studio Batch plan) lets you queue multiple files and convert them all in one go — unattended. Drop in 50 clips and photos, set your ratio and fill mode, pick an output folder, and walk away. It's designed for agencies and creators reformatting large content libraries for new platforms.

Can I use one licence on multiple machines?

Yes — your licence covers personal use on your Mac and Windows machines. The Creator licence includes 1 key; Studio and Studio Batch include 5 keys for teams.
