Are files uploaded for this tool?

This browser tool processes the selected media locally on this device. The file is not uploaded to ArtPlayer servers for this workflow.

Will the export have a watermark?

No. ArtPlayer browser tools do not add watermarks to exported files.

Why can processing take time?

The work runs in your browser, so speed depends on your device, browser, memory, source size, and the export settings needed for the result.

Which browsers work best?

Recent Chrome, Edge, and other modern Chromium browsers usually work best for heavier browser media processing.

What should I try if a large file fails?

Try a smaller source, close other heavy tabs, reduce resolution or duration first, and keep the tab open until the export finishes.

How do the compression presets change quality?

Quality keeps more detail, Balanced is the default, and Small aims for a smaller MP4 with more visible compression.

What output format will I get?

The tool exports an H.264/AAC MP4 so the compressed video works in common players and sharing flows.

Can I compress a video for Discord or email?

Yes. Start with the Small preset, then resize or trim the clip if the exported MP4 is still above your target upload limit.

Will compression change the resolution?

Quality and Balanced limit video height to 1080 pixels; Small limits it to 720 pixels. Taller videos are scaled down proportionally; smaller videos are not enlarged.

Can I guarantee a file below a specific size?

No. Presets do not target an exact size. Check the exported file size; use Small, resize, or trim and export again if it exceeds your upload limit.
