# TryDocsy — Browser-Based Offline File Processing Tools > TryDocsy is a free website of PDF, image and file-conversion tools that run entirely in your web browser, so your files are processed on your own device and never uploaded. It also includes photo and signature resizers preset to Indian government-exam specifications. TryDocsy (https://trydocsy.com) lists 126 tools: 32 PDF tools, 30 image tools, 6 AI and utility tools, 42 file converters and 16 exam-photo and form tools, including preset pages for 15 exams. Every tool runs in the user's browser using WebAssembly and client-side JavaScript, so file contents are never uploaded to a server. ## What is TryDocsy for? Use TryDocsy when you need to work with a PDF, image, or document file and want it done privately, instantly, and for free — without installing software or uploading sensitive files to a third-party server. It is a direct, no-upload alternative to tools like Adobe Acrobat online, Smallpdf, iLovePDF, and PDF24. **Best for:** privacy-sensitive documents, offline use, Indian government-exam photo/signature resizing, Aadhaar/PAN card printing, and quick one-off PDF/image edits. - **Technology**: WebAssembly (Wasm), HTML5 Canvas, client-side PDF/Image libraries (Tesseract.js for OCR, pdf-lib, pdfjs-dist, @imgly/background-removal, JSZip). - **Privacy Model**: Zero document uploads: file contents never reach a TryDocsy server, so they are never stored or logged. The site itself uses Google Analytics for page views and anonymous tool events (tool name, file extension, a coarse size bucket; never file names or contents) and Google AdSense for ads (see https://trydocsy.com/privacy). The no-upload claim is verifiable: https://trydocsy.com/how-we-protect-your-files walks through checking the browser's network tab. - **Offline**: Installable as a PWA. A tool works offline once you have used it while online, because the service worker caches only the pages and code your browser has fetched. OCR language data downloads the first time you run OCR; the background-removal model loads from staticimgly.com, which the offline cache does not store. The file itself is never uploaded. - **Pricing**: $0 / Free, no premium plans, no registration, no watermarks, no daily task limit. Each tool sets its own file-size cap: most PDF tools accept 100 MB, most image editing tools 20 MB, Compress Image 50 MB and MP4 to GIF 200 MB; 3D Model to ASCII accepts models up to 1 GB. Very large files can still run out of memory on phones. - **Availability**: Accessible instantly in any modern desktop or mobile browser. --- ## When TryDocsy fits, and when it doesn't It fits when: - **The file should not leave the device.** Processing runs in the browser, so file contents are never uploaded; https://trydocsy.com/how-we-protect-your-files shows how to confirm this in the network tab. - **The connection is unreliable.** A tool works offline once you have used it while online. OCR language data downloads the first time you run OCR; background removal loads its model from staticimgly.com, which the offline cache does not store. - **An Indian government-exam form needs a photo or signature at exact pixel and KB limits.** Each preset page under /exam/ (listed below) gives the specs, the official source they were checked against and the date of that check. Requirements change each recruitment cycle, and the official notification is the authority. - **The job is one file or a handful, done once, without an account.** There is no sign-up, no paid plan, no watermark and no daily task limit; each tool has its own file-size cap. It does not fit when: - **A compressed PDF must stay searchable.** /pdf/compress re-renders every page as a JPEG image, so text in the output can no longer be selected or searched. - **The document is handwritten.** OCR uses Tesseract.js, which is trained on printed text; handwriting and cursive come out garbled or missing. - **The work is a server-side or batch job.** There is no file-processing API or command-line tool. Every tool runs in a browser tab on the user's device and is limited by that device's memory. TryDocsy is not affiliated with UIDAI, the Income Tax Department, NPCI or any exam-conducting body. Its Aadhaar, PAN and UPI tools only process files the user supplies, on their own device. --- ## Tool Directory ### PDF Utilities - [/pdf](https://trydocsy.com/pdf) — Category hub for the browser-based PDF tools, grouped by task. - [/pdf/compress](https://trydocsy.com/pdf/compress) — Compress a PDF to a target size in KB/MB or with a quality preset, locally.

Use /pdf/compress for PDFs and /forms/signature for signature images (both listed above). ### Alternatives Comparison Pages - [/compare](https://trydocsy.com/compare) — Index of all comparison pages. - [/compare/adobe-acrobat-alternative](https://trydocsy.com/compare/adobe-acrobat-alternative) — Feature comparison of TryDocsy vs Adobe Acrobat Pro. - [/compare/adobe-sign-alternative](https://trydocsy.com/compare/adobe-sign-alternative) — Free, private alternative comparison of TryDocsy vs Adobe Sign. - [/compare/ilovepdf-alternative](https://trydocsy.com/compare/ilovepdf-alternative) — TryDocsy vs iLovePDF local-first comparison. - [/compare/smallpdf-alternative](https://trydocsy.com/compare/smallpdf-alternative) — TryDocsy vs Smallpdf comparison. - [/compare/pdf24-alternative](https://trydocsy.com/compare/pdf24-alternative) — TryDocsy vs PDF24 comparison. - [/compare/sejda-alternative](https://trydocsy.com/compare/sejda-alternative) — TryDocsy vs Sejda comparison. - [/compare/jpg-vs-png](https://trydocsy.com/compare/jpg-vs-png) — Technical analysis of JPG and PNG image formats. - [/compare/webp-vs-png](https://trydocsy.com/compare/webp-vs-png) — Technical analysis of WEBP and PNG image formats. - [/compare/heic-vs-jpg](https://trydocsy.com/compare/heic-vs-jpg) — Technical analysis of HEIC and JPG formats. ### Competitor Question Blog Posts - [/blog/is-smallpdf-safe](https://trydocsy.com/blog/is-smallpdf-safe) — Answers "Is Smallpdf safe?" and explains when to use a no-upload PDF workflow. - [/blog/ilovepdf-vs-smallpdf](https://trydocsy.com/blog/ilovepdf-vs-smallpdf) — Compares iLovePDF, Smallpdf, and browser-based PDF tools for privacy-sensitive documents. - [/blog/pdf24-sejda-alternative-no-upload](https://trydocsy.com/blog/pdf24-sejda-alternative-no-upload) — Explains PDF24, Sejda Web/Desktop, and no-upload alternatives. ### How-To Articles - [/blog/edit-text-in-pdf-free](https://trydocsy.com/blog/edit-text-in-pdf-free) — Why PDF text is hard to change, how to fix a typo or a date in place for free, and the honest limits (fonts, scans, rotated pages) to check before you send the file. - [/blog/make-scanned-pdf-searchable](https://trydocsy.com/blog/make-scanned-pdf-searchable) — We ran three test scans through in-browser OCR and measured word accuracy and file size.

A mirror is rendered from the same content objects as its page (its guide, FAQ, tool list or spec table), so its text is the page's own. Tool guide, article and exam mirrors leave out interactive demos and illustrations; hub mirrors leave out some page sections (quick answers, comparison tables, guides and demos). Append the page path to /md, for example https://trydocsy.com/md/pdf/merge for https://trydocsy.com/pdf/merge. Each mirror gives its page's canonical URL and last-updated date, and is served with noindex. Tool guide, article and exam pages point to their mirror with . Hub mirrors: - [/md/pdf](https://trydocsy.com/md/pdf) — PDF tools hub. - [/md/image](https://trydocsy.com/md/image) — Image tools hub. - [/md/convert](https://trydocsy.com/md/convert) — File converters hub. - [/md/forms](https://trydocsy.com/md/forms) — Student forms and exam photo tools hub. - [/md/government-exam-photo-size-requirements](https://trydocsy.com/md/government-exam-photo-size-requirements) — Exam photo and signature specification table. - [/llms-full.txt](https://trydocsy.com/llms-full.txt) — Every mirror in one text file: the /about facts, the exam specification table, then each tool guide and long-form article.
