Frequently asked questions
What is the blurred background?
The whole video stays visible and the empty space is filled with a blurred copy of it — much nicer than black bars.
Can I choose what stays in frame when cropping?
Yes. Slide the crop window left, centre or right (up/down for vertical videos); the preview updates instantly.
What resolution do I get?
The short side is up to 1080 px: 1080 × 1920 for 9:16, 1080 × 1080 for 1:1, 1080 × 1350 for 4:5. Smaller sources are never upscaled.
Is it really free?
Yes. These tools are completely free — no sign-up, no credits, no watermark. Your file is processed on your device, so it costs us nothing.
Is my file uploaded anywhere?
No. Your file is processed in your browser and never leaves your device. The internet is only used to open the page.
Is there a file limit?
Videos up to 2 GB and 30 minutes. Processing time depends on your device; keep the tab open for long videos.
Which browsers are supported?
Works best in current Chrome, Edge and Opera. Some video tools are limited in Safari and Firefox; a tool tells you clearly when your browser can't run it.
