What this page is
yelefile is a free file-processing utility. We work hard to make every tool accurate, but we are not infallible — tools can produce unexpected output. Before relying on a result for anything important, verify it.
Output correctness is not guaranteed
Concrete examples of what can go wrong, by tool family:
- PDF compression may strip rare embedded fonts, color profiles, or interactive form fields.
- PDF merging may not perfectly preserve bookmarks, internal links, or signed annotations.
- PDF splitting follows page boundaries; documents with complex page-tree structures may not split as a flat PDF reader would suggest.
- OCR may misread low-quality scans, multi-column layouts, math, or Indian-script text mixed with English. The output is a best-effort transcription and is not legally certified.
- Office → PDF conversion may render fonts and formatting differently than Microsoft Word, Excel, or PowerPoint.
- Image and audio compression are lossy by design; expect quality loss roughly proportional to the size reduction.
- Video conversion, GIF, and frame extraction are timing-sensitive; our video processor may pick the nearest keyframe rather than the exact frame you asked for.
What "verify before using for critical purposes" means
Open the result, scroll through it, and compare to the original. For legal, medical, financial, or government documents, have a competent professional review the output before submitting or relying on it.
Not professional advice
yelefile is a file-processing utility. We do not provide legal, medical, financial, tax, or government-filing advice. If you OCR an income-tax form, the OCR text is not tax advice.
