Upload a lab file, practical file or assignment PDF. Tell iLoveLabFile what to find and what to replace it with — it edits the text directly, so formatting, tables and diagrams stay exactly as they were.
Use the exact text as it appears in the PDF for a reliable match.
You're telling iLoveLabFile: “find this exact text and replace the first copy of it on every page it appears on.” That's the common case for a repeated student detail in a multi-page academic file.
It keeps the edit predictable. If a page repeats the same name several times, iLoveLabFile won't blindly overwrite every copy — it updates the first occurrence on that page and leaves the rest untouched.
Names, enrollment numbers, roll numbers, registrations and course details.
Student details, experiment records and repeated academic information.
Update student and subject information without rebuilding the PDF.
Batch, section, student and course information in workshop documents.
iLoveLabFile is a free online PDF text editor for targeted corrections. Students at GGSIPU — Guru Gobind Singh Indraprastha University and DTU — Delhi Technological University use it to change a name in a PDF, replace an enrollment number, update a roll number, correct a registration ID or fix a course code across an entire lab file, practical file or workshop file — without retyping or reformatting the document.
The processing is deliberately simple to reason about: for each Find → Replace pair, iLoveLabFile searches the PDF page by page and changes only the first matching occurrence on each page. That keeps results predictable on documents where the same student detail repeats on every page, which is the normal shape of a GGSIPU or DTU B.Tech practical file.
No. The current behavior replaces only the first matching occurrence on each individual page.
Yes — it's commonly used to change a name, enrollment number or roll number that repeats on every page of a GGSIPU or DTU lab file, practical file or workshop file.
The first match on each page can be changed, so the same Find value may be replaced once on page 1, once on page 2, and so on.
Yes. Add multiple Find → Replace pairs before submitting the document.
