CleverUtils
Free online file converter for 200+ formats, no signup
What is CleverUtils?
CleverUtils is a free online file converter built for people who just need a file in a different format without installing software or creating an account. It covers more than 200 converters across audio, video, images, documents, ebooks, archives and 3D models, so most everyday conversion jobs can be handled in one place.
Typical tasks include turning a PDF into an editable Word document, extracting the audio track from an MP4 as an MP3, converting iPhone HEIC photos to JPG so they open anywhere, or changing an ebook from EPUB to a format your reader supports. You upload a file in the browser, pick the target format, and download the result. There is no signup, no watermark on the output, and no limit designed to push you toward a paid plan.
Privacy was a design priority from the start. Uploaded files are processed only for the conversion you asked for and are deleted automatically within two hours, so nothing lingers on the server after the job is done.
For developers, CleverUtils also offers a free REST API that works without an API key. It is useful for scripts, CI pipelines, internal tools and small automations where you want to convert files programmatically instead of clicking through a web page. Documentation with request examples is available on the site.
There is also an MCP server, which lets AI agents and assistants that support the Model Context Protocol call CleverUtils directly to convert files as part of a larger workflow. This makes it easy to plug format conversion into agent-based tooling without writing custom glue code.
CleverUtils was started in 2024 in Kyiv by Oleksiy Savich as a simpler, lighter alternative to heavier conversion services such as Convertio. The goal is straightforward: fast, honest file conversion that respects your time and your data, available to anyone with a browser, whether you are a student, a designer, an office worker or a developer.

Over the next two and a half years I built and launched five products that made in total a whopping zero dollars. It taught me three fundamental things. Firstly, distribution matters. Secondly, monetization matters from day one. Thirdly, you need to focus on building painkillers, not vitamins.
Monetize from day one — lesson learned from five products that made zero dollars
Rob's hard-won rule after 5 zero-dollar launches: charge from day one. No indefinite free tier, no 'we'll figure out pricing later.' Willingness-to-pay is a product hypothesis that must be tested on launch day — every month you defer it is another month of building blind.

Warm a new TikTok account by consuming niche content before your first upload
Actively engaging with niche content trains the TikTok algorithm to correctly categorize the account and avoids shadowban penalties before the first real video goes live. This pre-upload step costs nothing but meaningfully increases distribution reach on the videos that matter.
