True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.
LaunchEdit text in place, sign, redact, fill forms, and reorganize PDF files in your browser — all on your device. No upload, no subscription.
Drop two versions of a contract or drawing set. Moved notes read as moves, changed values light up digit by digit, and hidden text is named.
LaunchSide-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Drop a Gerber ZIP, an ODB++ .tgz or an IPC-2581 .xml and inspect every layer — compare revisions, snap-to-pad measure, run DRC and preview the board in 3D.
LaunchOpen Gerber, Excellon, ODB++ and IPC-2581 PCB files. Inspect layers, measure traces, run DRC, export to PNG / SVG / DXF.
Open a .step / .stp part and it measures itself: volume, thinnest wall, draft and undercuts on load, and a hole list with a BOM in one click. Measure, section, export STL.
LaunchOpen a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Compress, merge, split, convert, and manipulate PDF files.
Resize, compress, convert, and transform images.
Convert, compress, and cut audio and video — MP3, WAV, MP4, WebM, Opus — all in your browser, nothing uploads.
Simulate a canning process down to its F0 sterilizing value.
Encrypt files, share encrypted notes as links, and inspect tokens, IDs, and Windows event logs.
Analyze packet captures, move files between devices, and console into network gear — nothing uploads.
Scan receipts into an expense ledger — your receipts and spending stay on your device.
View, measure, and repair CAD and 3D files — STEP, STL, OBJ, PLY, GLB, 3MF, DXF, and Gerber — right in your browser. Nothing uploads.
True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.
Launch PDF Editor
Yes. Editing is free with no signup: text, signatures, forms, redaction, page operations, annotations, OCR, and export.
No. The editor runs entirely in your browser. PDF rendering, edits, OCR, and export all happen on your device. Nothing leaves the tab.
It covers the everyday PDF jobs: edit text in place, fill and sign forms, redact, reorder, rotate and delete pages, annotate, OCR scanned PDFs, and export. It skips niche features (visual form builder, PDF/X prepress, PDF JavaScript actions). The trade-off is free, local, and faster on real workflows.
PDFs up to 100 MB open smoothly on most devices. Beyond that, the editor still works on capable devices but performance depends on your RAM.
Yes — true in-place edit in your browser. 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).
