Why use ToolzyLab

Your files stay on your device

The image and PDF tools do their work in your browser, so photos and documents aren't uploaded to a server. There are three exceptions. The HTTP header checker has to request the URL you type, the currency converter downloads exchange rates, and optional AI buttons send text only when you click them.

Free, with no account

Every tool is free to use without signing up. Converted images and PDFs come out without a ToolzyLab watermark, and you download them straight from the page.

Batches, not one file at a time

Most image converters take up to 500 files in one go and hand them back as a ZIP. Merge PDF combines up to 200 files, and JPG to PDF puts up to 300 images into a single document.

What can you do with ToolzyLab?

Each tool does one job and shows the result on the same page. Here's what people use them for most:

  • Convert photos. Turn iPhone HEIC photos into JPG with the HEIC to JPG converter, or switch between WebP, PNG, JPG and SVG.
  • Meet an upload limit. Get a photo under a set size for a form with Compress Image to 100KB, or change its pixel size with Resize Image.
  • Work with PDFs. Convert Word, Excel and images to PDF, get editable text back with PDF to Word, and merge, split, compress or password protect files.
  • Check and clean text. Count words and reading time, check a post against character limits, and join lines broken by a PDF copy.
  • Format code and data. Validate JSON, beautify HTML, CSS and JavaScript, and decode Base64, URLs and JWTs.
  • Do quick sums. Work out an age, a tip, a loan payment or a percentage, and convert units, currencies and time zones.

Questions people ask

Are ToolzyLab's tools really free?

Yes. Every tool is free to use with no account and no sign-up, and converted images and PDFs don't get a watermark.

Are my files uploaded to a server?

No. The image, PDF, text and calculator tools process everything in your browser, so your files stay on your device. Only the HTTP header checker, the currency rate download and optional AI features contact a server.

Do the tools work on a phone?

Yes. They run in mobile browsers such as Safari and Chrome, with nothing to install. A phone has less memory than a computer, so split very large batches into smaller groups.

Can I convert several files at once?

Most image converters accept up to 500 files or 2 GB in one batch and give you a ZIP. The compress-to-size tools take 50 images at a time, and Merge PDF accepts up to 200 PDFs.

Which file formats can ToolzyLab convert?

Images in HEIC, JPG, PNG, WebP and SVG, plus PDF to and from Word, JPG and plain text. Excel (.xlsx, .xls, .csv) and .txt files can also be turned into PDFs.

Do I need to install anything?

No. Open the tool's page, add your file or text, and download the result. There's no app, extension or plugin to install.
