Sejda

editing PDF documents with Sejda, where the online PDF editor page says it can fill out PDF forms online, change PDF text, add text, edit existing PDF text, add images, create and edit hyperlinks, and annotate PDF pages, and the tool list also describes creating free PDF forms, making existing PDF documents fillable, adding text, links, images and shapes, and a Whiteout tool that hides content; the scope is the documented text, image, link, annotation and form editing, and two boundaries are kept: the Whiteout tool is recorded elsewhere as covering content rather than removing it, and editing text already in a scanned page is not claimed because the editor works on the PDF text layer while OCR is the separate job

merging and splitting PDF documents with Sejda, where the Merge tool combines multiple PDFs and images into one document, the Alternate and Mix tool mixes pages from two or more documents alternating between them, the Organize tool arranges and reorders PDF pages, and the split tools extract pages by page range, by bookmarks, by splitting two-page layouts, by target file size and by text occurrences; the free tier limits combining to 30 files and 50 pages, and the scope is the documented merge, mix, organise and split operations, with no claim about preserving signatures, forms or annotations across a merge

compressing PDF documents with Sejda, where the Compress PDF page says the compression algorithm optimizes images, removes unused fonts and images, and saves optimized images at JPEG quality 65 percent by default, with a Good or Best image-quality option, a default 72 PPI image resolution with 144, 288 or 720 PPI options as the maximum image resolution, and a grayscale image conversion option for smaller files; the scope is the documented image, font and image-cleanup compression with the named quality and PPI controls, and no size-reduction percentage or lossless guarantee is claimed

converting PDF documents with Sejda, where the tool list documents PDF to Excel and CSV for table extraction, PDF to JPG, PNG or TIFF images, PDF to PowerPoint, PDF to Text, and PDF to Word DOC with Keep layout and Optimize for legibility options, plus HTML to PDF, JPG to PDF and Word DOCX to PDF; the free tier limits a conversion to 20 pages, and the scope is the documented conversion directions and the two PDF-to-Word layout options, with no fidelity guarantee and no conversion of formats not listed

signing PDF documents with Sejda, where the Fill and Sign PDF page says users can create a signature by typing their name and selecting from over 10 handwriting styles, by drawing with a mouse, trackpad or pointer device, or by uploading an image of their signature, and then place and resize the signature on a PDF page and fill out PDF forms; the scope is those documented electronic-signature methods and form filling, and no certificate-based digital signature, timestamping, long-term validation or audit-trail claim is made

running optical character recognition with Sejda, where the OCR PDF page says the tool converts PDF scans to searchable text and PDFs, that users select the language of the document so ambiguous words are resolved using the language dictionary, that the output can be a searchable PDF, a plain text file or both, and that the searchable PDF contains invisible text overlaid on the original images at the correct locations; the page suggests inspecting recognised text rather than promising accuracy, the free tier is limited to 10 pages per OCR task while paid plans allow up to 100 pages, and the scope makes no language-count or accuracy guarantee

protecting PDF documents with Sejda, where the Encrypt PDF page, at /encrypt-pdf, offers password protection plus an admin password to change permissions, encryption levels of Medium RC4 128 bits, Medium AES 128 bits and Strong AES 256 bits, and PDF reader permissions for modifying, copying text and graphics, printing, high resolution printing, filling forms, commenting, and inserting, rotating or deleting pages; the page itself warns that some PDF readers ignore these permissions and that they may not be honoured or enforced at all times, and the scope keeps that warning as the boundary rather than claiming enforcement
