Why this site exists
Most free online tools make you upload your file to their server, wait in a queue, and then add a watermark or ask you to sign up. That's slow, and it means strangers handle your contracts, ID photos and bank statements.
Browser Tools does the work in your own browser instead. Compressing a photo, merging PDFs, making an invoice or working out a loan happens on your device, so it's instant and private, and it keeps working even if your connection drops after the page has loaded.
What you'll find here
- Image tools: compress to an exact size, resize for passports and social media, convert HEIC, WebP and AVIF.
- PDF tools: Word to PDF, PDF to Word, PDF to JPG, merge PDFs, photos to PDF.
- Business tools: invoices, quotes, freelance contracts and pricing calculators.
- Calculators: loans and mortgages, savings, crypto gains, BMI, calories, macros, GPA and more.
- Text tools: word counter, formatting remover, case converter and list cleaners.
How we keep it accurate
Calculators use standard published formulas (for example Mifflin-St Jeor for calories, the US Navy method for body fat and the standard amortization formula for loans), and every tool is tested automatically in a real browser before each release. Results are estimates for planning, not financial, medical, tax or legal advice.

Frequently asked questions
Is it really free?
Yes. Every tool is free with no account, watermark or daily limit, except Text to Speech, which has a free daily allowance because each voice costs us money to make.
How can it work without uploading my files?
Your browser is a powerful computer. The tools use open-source engines (FFmpeg for video, pdf.js and pdf-lib for PDFs, your browser's own image codecs) that run inside the page, on your device.
How is the site paid for?
Running tools in your browser costs us almost nothing. The site may show ads in the future, and some advanced AI features may become part of an optional paid plan.
Can I use the results commercially?
Yes. Files, invoices, barcodes and QR codes you make are yours to use for anything.
