What is this website?
Doblique is a free, browser-based toolkit for everyday PDF, image, text, and calculator tasks. Unlike many sites that upload files to a server first, its tools read and convert files inside your browser on your device. Tools are split by one job each—about 22 across PDF, image, text, developer, calculator, and utility categories. It fits people who need a quick file job without creating an account.
Core features
- Merge, split, and delete PDF pages, plus JPG↔PDF and PDF→JPG conversion
- Compress, crop, resize, and convert images, including HEIC to JPG
- Word and character counts, case conversion, and JSON formatting
- Calculators for age, percentages, dates and time, compound interest, and loans
- QR code and password generators; processing stays in the browser, with no signup and no watermarks on exports
Common use cases
- Students or writers: count words before a deadline, or fix ALL-CAPS text into sentence case
- Office work: merge PDFs, remove extra pages, or pack images into a PDF
- Phone users: convert iPhone HEIC photos to JPG, then compress for email or the web
- Developers: paste JSON temporarily to format and inspect it
- Personal planning: rough out interest or loan payments with the built-in calculators
Who is it for?
- People who occasionally edit PDFs or images and do not want desktop software
- Users who prefer not to upload documents to a third-party server
- Anyone who wants the same tools in a phone or desktop browser without installing anything
- A poorer fit: batch automation, server APIs, or files over the site limits (about 100 MB for most tools; about 250 MB for Split PDF and Delete PDF Pages)

- Account and watermarks: whether signup is required and whether exports are marked
- Coverage: PDF, images, text, and calculators together versus a single-category tool
- Size limits: whether typical files fit the stated per-file caps
