Make sense of your files. Find clear steps, worked examples and checks for PDFs, images, spreadsheets and everyday document tasks.
Choose watermark wording, placement and opacity, then check small text and print output. Learn why a visible mark is not encryption or proof of authenticity.
Read the guidePlan a PDF assembly, distinguish deletion from extraction, rotate misplaced pages and verify the final sequence before adding page numbers.
Read the guideCompare lossless PDF optimization with raster compression. Check actual bytes, small text and interactive features, and handle a target that cannot be reached.
Read the guidePrepare a HEIC batch, convert a test image, download the results and verify counts, orientation and detail. Keep originals when creating compatible JPG copies.
Read the guideUse Preview to export a HEIC as JPEG, or convert a supported batch in the browser. Check format, dimensions, orientation and metadata before sharing the copy.
Read the guideCreate a readable PDF from a note on Android. Set page size and spacing, check long lines and characters, and find the downloaded file before sharing.
Read the guideCalculate an exact crop using X, Y, width and height. Learn when to crop or resize, with a 1600 × 1200 example and checks for image upload requirements.
Read the guideDiagnose content, page breaks, section breaks and the final paragraph behind a blank Word page. Check headers and numbering after removing it.
Read the guideCompare a signature image with a certificate-backed digital signature. Learn what validation checks and why editing a signed file matters.
Read the guideSeparate decoding failures from broken links, then check QR margins, contrast, density and print quality. Test the actual final size before printing a batch.
Read the guideFind a HEIC file on Android, convert a small batch and share the actual JPG download. Troubleshoot picker visibility, missing files and decoding failures.
Read the guideChoose an in-cell picture or configure a floating image, then test sorting and filtering. Learn why inserting an image does not extract its values into cells.
Read the guideCombine finished PDFs with a clear file order, check page boundaries and mixed orientations, and understand the limits for forms, bookmarks and signed files.
Read the guideAdd page numbers in Word, distinguish hiding the cover number from restarting the count, and check section breaks. Add visible numbering to an existing PDF.
Read the guideCheck whether a PDF contains selectable text, convert it to DOCX, and repair reading order, tables and page breaks. Scans need a separate OCR step.
Read the guideDecode a saved QR image, keep its quiet zone when cropping, and inspect the destination before opening it. Includes a practical route for QR codes inside PDFs.
Read the guideDiagnose what makes a file large, choose resizing or compression, and verify a byte limit without losing essential detail. Includes a practical target example.
Read the guideInspect author, title and photo metadata, remove supported fields, and check the saved copy. Distinguish metadata cleanup from redaction and full sanitization.
Read the guideExport Word to PDF, choose relevant options, inspect fonts and links, and append it to an existing PDF. Learn why pasted text does not preserve Word layout.
Read the guideTurn a table screenshot into editable cells. Prepare a clear crop, correct OCR mistakes, and check amounts, dates and row alignment before using the workbook.
Read the guideAdd a visible signature to Word, anchor it reliably, export and inspect the final PDF. Distinguish an image from a certificate-backed signing workflow.
Read the guideChoose between one file per page and a selected page range. Check physical page positions, filenames and output counts before sharing a split PDF.
Read the guideConvert a list or delimited text into an XLSX workbook. Choose separators, preserve leading zeros, and check quoted commas, blank fields and line breaks.
Read the guideDistinguish a PDF opening password from editing restrictions, create an authorized unlocked copy, and verify the output. Includes password and sharing checks.
Read the guideCompare three downloadable PDFs with the same table stored as text, an image or an editable form. Check which features your conversion needs to preserve.
Read the guideEvery guide exists to answer a question a tool page cannot answer well at the same time as being a tool. A tool page should let you do the thing; a guide can explain why the thing behaves the way it does — why a QR code that looks fine will not scan off a printed card, why splitting a PDF beats compressing it, what a HEIC conversion actually costs you.
They are written against what the tools genuinely do. Where something is not possible — recovering the page under a flattened watermark, reading handwriting with OCR, undoing JPEG compression — the guide says so rather than routing you to a tool that will fail quietly. Limitations are more useful than features when you are trying to finish a task.
Start from a category if you are not sure what you need: PDF tools, image tools, OCR and extraction, text and data, or developer utilities. Or see every tool in one list.
