SEO guide
Fix conversion errors on PasteGrab — preset selection, source limits, and retry steps for MP3 and MP4 jobs.
Overview
PasteGrab processes public URLs server-side. Conversion failures often trace to unsupported pages, corrupt short links, or exceeding size/duration limits.
Pick your output preset before preview — switching after queueing can cause unexpected results. MP3 jobs need a video URL with an audio track.
Check /docs/limits for fair-use caps on file size and clip length.
