Stapler is an offline PDF toolkit. Everything runs on your device: nothing is uploaded, there is no account, and the extension asks for no permissions.

This release covers everything since 0.2.1. Version 0.3.0 was never published on its own.

• Fast web view. An option in the review before saving puts page 1 first, so a browser can start showing a PDF before the rest has downloaded. It is off by default, which keeps files smallest.
• Colour option in Compress. Choose shades of grey or black and white for scanned documents. Stapler never saves a file larger than the original, and it tells you which pages could not be converted.
• Exact pixel size in Image to size and PDF to images. Set a width and a height, with the proportions locked by default. If a size target can't be reached, Stapler now says how far off it was.
• Folder search reads scanned pages. This is optional. OCR runs only after you approve the one-time download of its language model, and recognized text is marked as such in the results.
• Safer sharing on the web app. The installable web app now asks before opening files shared to it that it cannot confirm came from your device.

• Redaction is more thorough. It now also removes content hidden inside repeating patterns, under thick or widened lines and outlined text, and under image masks. Its built-in check fails if anything is left behind, and redacted files no longer double in size.
• Honest file sizes. Image to size, Grayscale and Compress never quietly save a file larger than you started with. Their "Reached" messages are measured on the saved file, and sizes use KB and MB (1 KB = 1000 bytes) everywhere.
• Your work is safer.
• Undo after saving works correctly.
• "Clear all local data" now tells you if anything could not be deleted.
• Restoring a session respects the document limit.
• Repair keeps your edits.
• Web app updates. The web app no longer mixes old and new code after an update, and other open tabs reload safely.
• Face and logo blur now reaches images in comments and fill patterns.
• Form fields line up on cropped and rotated pages.
• Read aloud follows page edits.
• Compare exports use the real page sizes and can be cancelled cleanly.
• Speed. Scrolling through large documents and merging big files is smoother, and heavy work no longer freezes the screen.
• Accessibility. Tooltips are accessible to screen readers, and every screen passes automated accessibility checks in light and dark themes.

The Firefox package passes Mozilla's add-on validator with 0 errors and 0 warnings, and every package is about 275 KB smaller than the first 0.3.0 build.

Bug-fix release. No new tools, no behavior changes to any existing tool's output —
this release closes gaps a recent internal audit found in state handling and
resource cleanup, and finishes translation coverage that shipped incomplete in 0.2.0.

• Switching tools or documents while a job was running could clobber the active-job
  progress bar, defeat the unsaved-changes guard, leak Compare's second file source,
  or let a slow Sign panel form-field fetch overwrite state for a document you'd
  already switched away from.
• A batch of concurrency and edge-case issues found across an internal audit:
  concurrent confirmation dialogs could hang forever, OPFS unavailability crashed
  the app instead of falling back to memory, undo/redo history could be corrupted
  by overlapping operations, and several tools (compression, redaction, scan
  cleanup, OCR, batch processing) mishandled degenerate or adversarial inputs.
  Full details in docs/AUDIT-FINDINGS.md and docs/AUDIT-EDGE-CASES-2026-09-15.md.
• Document and page-selection state updates are now batched, session auto-save no
  longer re-enters itself under rapid changes, and worker job handles and render
  canvases now release their memory immediately instead of waiting on garbage
  collection.

• Completed translations for all 10 supported locales — 173 strings added by the
  Word/Excel/PowerPoint converters and the export-review flow were previously
  English-only outside the default locale.

Every fix in this release is covered by an existing or new automated test.
tsc --noEmit, eslint, prettier --check, the design-token/contrast/invariant
checks, all 1425 unit tests, the automated QA-05 structural PDF validation, and
the 8-test zero-network e2e suite all pass against the built extension.

New: six beta PDF conversion tools, all fully offline like everything else in Stapler.

• PDF ⇄ Word (.docx) — structural conversion with headings, paragraphs, tables and images; bold/italic/hyperlinks preserved.
• PDF ⇄ Excel (.xlsx) — detects table-like text and writes it to sheets, or draws a workbook's sheets as a paginated grid.
• PDF ⇄ PowerPoint (.pptx) — places each page's text/images onto slides, or draws each slide as a PDF page.

Every conversion is labeled beta, states plainly what it does and doesn't preserve, and shows a mandatory preview before the save button unlocks — so you always see the actual output before it's written. No permission and no network request was added.
