Ahrefs Domain Rating set in type 3 Nov 2026, reset 2 Nov 2026.
Collection of 118 free online tools including PDF converters, image processors, QR code generators and calculators that run privately in your browser.
Assen Tools is a collection of 118 free online tools and 130 how-to guides for students, job seekers, office workers, small businesses and developers. Each tool performs one specific task, from compressing or merging PDFs and making passport photos to converting units and counting words. Most tools run entirely in your browser, keeping files private on your device with no sign-up or watermarks required.
The site was created to solve a common problem: simple jobs that require visiting many different websites. Instead, Assen Tools consolidates everyday file, photo, and calculation tasks into one free platform. Tools follow official specifications for passport sizes, resume formats and conversion formulas. The site is funded by advertisements and is maintained by its founder, a freelance web developer.

Measured after Assen Tools went live on Zivaro Launch on 2 November 2026.
Day 1 since launch. Next receipt: day 30, 2 Dec 2026. These are measurements, not proof of cause: many things move these numbers. Figures we have not measured are left out.
Most tools run entirely in your browser, so your files never leave your device. A few tools like the HTTP status checker and website speed test contact another website, but the server only makes requests for the address you enter.
The tools are free because the site shows a small number of clearly labelled advertisements. Businesses can book ad placements directly, and some ads promote the founder's own businesses.
Yes, passport and visa sizes, resume formats and conversion formulas follow official sources, which are linked on the tool pages where they apply.
Guides show the date they were last updated. If you spot a mistake or something out of date, you can report it and it will be corrected.
