We list trade-offs explicitly. Browser-based + privacy-first means some features that need a server (cloud sync, named-account workflows) won't ship here.
Yes. Core editing is free with no signup: text, signatures, forms, redaction, page operations, annotations, merge/split, OCR, basic export. Power features (batch processing more than 5 docs, files larger than 100 MB, layout-preserving Word export, AI summarization) ship as a paid Pro tier.
No. The editor runs entirely in your browser. PDF rendering, edits, OCR, and export all happen on your device. Nothing leaves the tab.
The editor covers the 15 actions that account for ~90% of Acrobat use cases: edit text in place, fill and sign forms, redact, reorder pages, annotate, merge, split, OCR scanned PDFs, and export. It skips Acrobat features that few people use (form builder, PDF/X prepress, PDF JavaScript actions). The trade-off is free, local, and faster on real workflows.
Free tier handles PDFs up to 100 MB. Beyond that, the editor still works on capable devices but performance depends on your RAM. Pro tier removes the soft limit.
Yes — true in-place edit in your browser via pdfium-wasm. Click a word, type the replacement, save. The editor rewrites the underlying content stream and keeps the original font, size, color, and position. Adjacent text on the same line shifts right or wraps to the next line if your edit makes the run longer, and following paragraphs shift down to make room. When the original font is a tight subset that doesn't include glyphs your new text needs, the editor falls back to a built-in base-14 font in the same family (Helvetica / Times / Courier) so you never see missing glyphs. Most online editors stamp a white box and draw new text on top; this one rewrites the bytes.
Yes. Redactions remove the underlying bytes from the saved PDF, not just cover them visually. Re-extracting text from a redacted file will not return the redacted strings.
After the first visit, yes. Install Loft as a PWA and the editor works without an internet connection. The editor engine, fonts, and any cached models are stored locally.
The editor auto-persists your most-recent session. On reload you will see a "Restore last session?" prompt. Earlier docs in the tab are not persisted (privacy default).
