Start with the right source
Clean scans, sharp images and text-based PDFs give browser tools more useful information to work with. A converter cannot recreate detail or document structure that is absent from the source.
PDF, image, text and calculator utilities with practical guidance so you know what each tool can—and cannot—do.
Combine multiple PDFs into a single file.
Reduce PDF file size for email or upload limits.
Erase the background from a photo automatically.
Shrink JPG or PNG file size, keep quality.
Create a scannable QR code from text or a link.
Count words, characters and reading time.
Validate and pretty-print JSON.
Three common percentage questions, answered instantly.
Convert, merge, split, compress, edit and secure your files.
Resize, compress, convert and clean up photos and graphics.
Count, convert case, generate and format written content.
Format, validate, encode and calculate for everyday tasks.
Clean scans, sharp images and text-based PDFs give browser tools more useful information to work with. A converter cannot recreate detail or document structure that is absent from the source.
Choose format, dimensions and file size based on where the output is going. A government upload portal, a website image and a print document have very different needs.
Automated conversion is convenient, not infallible. Check names, figures, small text, page order, signatures and formatting before sending an important document.
Every tool page now explains the actual browser-side method used by that specific utility, including what the code can and cannot preserve.
Each tool includes a short output checklist and a clear “use another method when…” boundary so important files are not treated like casual conversions.
Guides show concrete inputs, tradeoffs and checks for PDF workflows, image formats, text, developer tasks and calculations.
My Tools HQ is a browser-based utility site for common document, image, writing, developer and everyday calculation tasks. The tools are deliberately scoped: each page explains the useful use case, the technical limitations and a few checks that help prevent bad output.
Core file and text transformations are designed to happen on your device in the browser where the implementation allows it. That does not mean the website makes no network requests: normal page assets, fonts, open-source libraries or machine-learning models can be loaded from our site or third-party content delivery networks. Our Privacy Policy describes that distinction instead of making a blanket “nothing leaves your device” claim.
We also publish independent guides covering file formats, compression, PDF workflows, image resolution, hashing, Base64, JSON and calculator concepts. The aim is to make the utility useful even when the correct answer is “use another method for this particular document.”
