Guide and support

The basic flow is: add materials → organize pages → preview → rename and save a new copy.

Add and organize

Split and export a page as an image

Enter one group per line, such as 1-3 then 4-6, or a group like 1,3-5. Duplicate pages within or across groups, empty groups and out-of-range numbers are rejected. Preview and rename each result, then save or share each file. Unselected pages remain in the original workspace.

Select one page to export PNG or JPEG. The current output has a white background and a maximum longest edge of 2048 pixels. JPEG is lossy. Zoom in to check small text. Image export does not create searchable text.

Watermarks, cropping, paper and page numbers

Purpose watermarks, manual four-edge cropping, portrait/landscape A4/A5 fitting and page numbering first generate an independent preview. Confirm to apply and use undo if needed. Cropping hides portions outside the visible box; it is not permanent sensitive-data redaction. A purpose watermark does not prevent copying or certify authenticity.

Optional compression

Initiate compression only when needed. It re-encodes supported image streams and does not guarantee any target size or a smaller result. Inspect small text, stamps, QR codes and colors. An unmet size requirement is not success. If integrity checks fail, the candidate is not adopted; the organized version remains available to save.

Trial, unlock and restoration

Saving, limits and common questions

Saving prepares a new copy. After the system panel returns a location, open the actual result in Files. Cancellation keeps your preview. Do not deliberately rename back to an input original and approve replacement in the system panel. Opening a share panel does not prove the recipient saved the file.

Current engineering limits are 20 cumulative inputs, 50 MB and 200 pages per session; these are safeguards, not performance guarantees on every device. Detected encryption, interactive forms, digital signatures, annotations/links and some document-level interactive structures are rejected to avoid silent loss. OCR, Word conversion and PDF body-content editing are not provided.

The interface follows system/app language. Language switching does not translate PDF content, user filenames or watermark input. Save results you want across launches; automatic recovery of unsaved drafts is not promised.
