# ToolAcre > A set of small, single-purpose web tools that run entirely in your browser. No accounts, no uploads, no tracking. ## Principles - Each tool does one job and states plainly what it cannot do. - Files and text are processed in the browser. No tool uploads your data to a ToolAcre server; there is no such server. - 2 of 15 tools contact a third-party host by design, after an explicit action: Direct Media Downloader (https://toolacre.com/tools/media-downloader/); YouTube Thumbnail Downloader & Metadata Viewer (https://toolacre.com/tools/youtube/). Each states every request before it makes one. - No account system, so there is nothing to sign up for and nothing to delete. - Advertising and analytics are disabled in this build. - No ratings, reviews, testimonials, user counts or download counts exist anywhere on this site. ## Tools - [PDF Toolkit](https://toolacre.com/tools/pdf/): Merge, split, rotate, watermark and convert PDF files entirely in your browser. - [Direct Media Downloader](https://toolacre.com/tools/media-downloader/): Download a media file from a direct link, straight to your device, with the URL checked before anything is contacted. - [DCF Calculator](https://toolacre.com/tools/finance/): Educational discounted cash flow model driven entirely by your own assumptions. - [Browser Image & Drawing Editor](https://toolacre.com/tools/editor/): Crop, adjust, annotate and draw on images without uploading them anywhere. - [Image Converter & Compressor](https://toolacre.com/tools/image/): Convert between PNG, JPEG and WebP and shrink file size in your browser. - [Freelance Invoice Tool](https://toolacre.com/tools/invoice/): Build and export a clean freelance invoice or quotation as a PDF, in your own country's labels and currency, with data kept on your device. - [QR & Barcode Toolkit](https://toolacre.com/tools/qr/): Generate QR codes and Code 128 barcodes without a server round trip. - [CSV Cleaner](https://toolacre.com/tools/csv/): Tidy delimiters, headers, duplicates and encodings in spreadsheet exports. - [Text Toolkit](https://toolacre.com/tools/text/): Case conversion, diffing, counting, escaping and whitespace cleanup for text. - [Subtitle Toolkit](https://toolacre.com/tools/subtitle/): Convert, retime and clean SRT and VTT subtitle files in your browser. - [Image Metadata Privacy Tool](https://toolacre.com/tools/privacy/): Inspect and strip EXIF, GPS and other metadata before you share a photo. - [Social Image Resizer](https://toolacre.com/tools/social/): Resize and crop images to the aspect ratios social platforms expect. - [Developer Data Toolkit](https://toolacre.com/tools/developer/): Convert JSON, YAML, XML, TOML and CSV, edit HTML safely, calculate chmod modes, convert docker run to compose, build cron schedules, and inspect developer data. - [YouTube Thumbnail Downloader & Metadata Viewer](https://toolacre.com/tools/youtube/): Pull every thumbnail size and the public title, channel and embed details for a YouTube link. - [Password Generator](https://toolacre.com/tools/password/): Generate secure, memorable passphrases in your browser using the EFF wordlists and your browser's cryptographic random number generator. ## Machine-readable index - https://toolacre.com/api/tools.json ## Contact contact@toolacre.com
