Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

PDF Editor Offline

Why PDF Editor Offline?

Most PDF tools ask you to upload your document, create an account, or start a subscription. PDF Editor Offline is built for the opposite workflow: open a PDF on your own machine, make the changes you need, and export a new copy without sending the document to a third party.

  • Private by default: the desktop and source apps process files on your device.
  • Useful for everyday work: edit, annotate, fill, sign, merge, split, convert, OCR, and redact.
  • Free and open source: MIT licensed, with no account or recurring subscription.
  • Honest about results: risky operations can create a copy and report what was checked.

What can it do?

| Need | Included tools | | --- | --- | | Edit and mark up | Add text, images, drawings, highlights, comments, stamps, signatures, watermarks, and attachments. | | Fill and sign | Fill standard PDF forms, add a typed/drawn/image signature, or create a separately signed copy with your own certificate. | | Organize pages | Merge, split, extract, duplicate, reorder, rotate, crop, resize, number, compress, and remove blank pages. | | Convert files | Convert PDFs to Word, PowerPoint, Excel, images, Markdown, text, EPUB, SVG, or PDF/A, and create PDFs from common file types. | | Protect privacy | Remove metadata and selected hidden data, protect or unlock a PDF, and permanently redact sensitive text. | | Search and automate | Run local OCR, search documents, use the CLI/Python package, or connect through the local FastAPI API. |

The five guided workflows are Redact & Prove, Fill & Sign, Organize Pages, Sanitize & Share, and OCR & Search. The full capability matrix explains which features are stable, beta, experimental, or dependent on optional local tools.

Your documents stay yours

In desktop and ./start.sh source mode:

  • files are processed on the current device;
  • the app does not require an account;
  • there is no document telemetry or hidden cloud conversion service;
  • the local API uses loopback networking and a per-launch token;
  • high-risk workflows preserve the original and export a separate copy.

Docker and self-hosted mode process files on the host you choose, so their privacy boundary is that machine rather than necessarily the browser device. Read the privacy contract and threat model before using sensitive documents.

See the real app

A real local workflow loading a synthetic PDF, finding two sensitive text matches, permanently redacting them, and verifying that zero matches remain

This is the real local app using the public synthetic demo-redaction.pdf. It finds two test matches, permanently redacts them, and checks the exported result until zero matches remain. Reproduce it with the five-minute Redact & Prove guide.

Screenshots

| Edit a PDF locally | Find and redact sensitive text | | --- | --- | | Local PDF editor workspace | Local text search and permanent redaction |

| Clean private data | Merge and organize pages | | --- | --- | | PDF privacy cleanup tools | PDF merge completed locally |

Download the desktop preview

An unsigned 3.0.0 technical preview is available for people who want to try the desktop app before native code signing is complete. It is not the future stable signed release.

| Platform | Download | Important note | | --- | --- | --- | | Windows 10/11 x64 | Open the preview release | Unsigned NSIS .exe; Windows SmartScreen may warn or block it. | | macOS 11+ Apple Silicon | Open the preview release | Ad-hoc .dmg; not notarized. | | macOS 11+ Intel | Open the preview release | Ad-hoc .dmg; not notarized. | | Ubuntu 22.04/24.04 x64 | Open the preview release | .AppImage and .deb with checksums and provenance. |

Do not disable operating-system security solely to run the preview. Verify a download using the attached SHA256SUMS and the desktop distribution guide.

Quick start

Run the complete local web app from source:

git clone https://github.com/OthmaneBlial/pdf-editor-offline.git
cd pdf-editor-offline
pip install -e ".[dev]"
./start.sh

./start.sh chooses random loopback ports, creates a per-launch API token, starts the backend and frontend, and prints the local URL to open.

The Python package and CLI can also be installed from PyPI:

pip install pdf-editor-offline
pdf-editor-offline --version

The PyPI package contains the Python API and command-line tools. The visual editor runs from a source checkout or the desktop preview.

The npm launcher provides a short path to the desktop download and forwards automation commands to the separately installed Python CLI:

npm install --global pdf-editor-offline
pdf-editor-offline desktop
pdf-editor-offline doctor

You can also open the official desktop preview without a global install:

npx [email protected] desktop

The small npm package does not bundle the unsigned installers or a Python runtime. It opens the immutable 3.0.0 preview release for the visual app; CLI commands require the PyPI package shown above. Documents remain local and are never handled by the npm launcher.

Docker

docker pull othmaneblial/pdf-editor-offline
docker run --rm \
  -p 127.0.0.1:8000:8000 \
  -e PDF_EDITOR_OFFLINE_API_TOKEN="choose-a-long-random-token" \
  othmaneblial/pdf-editor-offline

CLI and Python automation

Common CLI commands:

pdf-editor-offline extract text input.pdf
pdf-editor-offline extract images input.pdf --output-dir ./images
pdf-editor-offline edit metadata input.pdf title "Quarterly Report"
pdf-editor-offline inspect-privacy input.pdf
pdf-editor-offline verify-redaction redacted.pdf --target "removed text"
pdf-editor-offline compare before.pdf after.pdf --output change-review.json

Python API:

from pdf_editor_offline import PDFConverter, PDFManipulator

converter = PDFConverter()
converter.pdf_to_word("input.pdf", "output.docx")

manipulator = PDFManipulator()
manipulator.merge_pdfs(["file1.pdf", "file2.pdf"], "merged.pdf")

Proof, limits, and trust

PDFs can contain complex fonts, forms, signatures, scripts, attachments, and unusual page structures. PDF Editor Offline publishes what it supports instead of pretending every transformation is perfect.

Complex fonts and layouts can lose fidelity; XFA is inspect-only; editing bytes can invalidate existing digital signatures; OCR, LibreOffice conversions, and Ghostscript operations require optional local tools. Keep the original and review the exported copy.

The project has evaluated SignPath Foundation as a possible free open-source Windows signing provider. No application has been submitted, and no terms have been accepted. Current Windows preview assets are not represented as SignPath-signed. macOS signing and notarization require a separate Apple Developer ID. See the code signing policy.

Develop and contribute

pip install -e ".[dev]"
python -m pytest
cd frontend
npm ci
npm test
npm run build

Run the complete local check with ./run_ci.sh. Contributions are welcome; start with CONTRIBUTING.md, or open an issue using a safe synthetic PDF instead of a private document.
