CleverUtils vs Lunatask: Which Is Better in 2026?

CleverUtils is a free online file converter for people who simply need a file in another format and do not want to install software, create an account or pay for a subscription. It runs in the browser on any device, so the same tools work on a work laptop, a home PC or a phone.

The site covers more than 200 converters across 100+ formats. For audio there are MP3, WAV, FLAC and M4A conversions. Video tools handle MP4, MOV, MKV, AVI and GIF, including turning a video into audio or a short clip into a GIF. Image converters work with JPG, PNG, WebP, HEIC, AVIF, SVG and common camera RAW files, which is handy when an iPhone photo will not open on a Windows machine. Document and PDF tools cover DOCX, XLSX, PPTX and EPUB, and there are also converters for archives, fonts and 3D models.

Beyond plain format changes, CleverUtils includes a set of PDF tools: merge several PDFs into one, split a long document, compress a file so it fits an email attachment limit, and unlock a PDF you have the right to edit. There is also a growing group of AI tools. You can remove the background from a photo, replace it with a new one, upscale a small image, clean up a noisy photo, reduce noise in an audio recording and turn speech into text.

Privacy is kept simple. Files are sent over HTTPS, processed on the server and deleted automatically within two hours. There is no signup, no watermark is added to the results, and you do not need to leave an email address to download a file.

Under the hood the conversions rely on proven open-source engines: FFmpeg for audio and video, ImageMagick for images, LibreOffice for office documents and Ghostscript for PDFs. This keeps the output predictable and close to what desktop tools would produce.

For developers, CleverUtils offers a free public REST API that does not require an API key, so a conversion can be added to a script, a build pipeline or a small internal tool in a few lines of code. There is also an MCP server, which lets LLM agents call the converters directly when a workflow needs a file changed from one format to another.

Typical uses include students converting lecture slides to PDF, freelancers sending clients files in the format they asked for, office workers compressing scans before emailing them, and creators extracting audio from video or preparing images for the web in WebP or AVIF.

CleverUtils is a solo project built in Kyiv, Ukraine, and positioned as a free alternative to Convertio, Zamzar and CloudConvert. New converters and tools are added regularly, and the changelog on the site lists what has changed. If you need a quick, private and free way to convert a file, CleverUtils is built for exactly that.

Lunatask is an all-in-one, privacy-focused productivity app that combines to-do lists, notes, habit tracking and mood tracking in a single, thoughtfully designed tool. It's built to help people manage their tasks and well-being together, with a gentle, encouraging approach that's especially appreciated by those who find traditional productivity apps stressful or who deal with challenges like ADHD. By bringing tasks, notes, habits and mood into one place — and respecting your privacy with end-to-end encryption — Lunatask offers a more holistic, humane take on getting organized.

The app covers the essentials of task and project management — capturing to-dos, organizing them, prioritizing and scheduling — alongside notes for capturing thoughts and information. But it goes further with habit tracking to help you build positive routines, and even mood tracking to help you notice patterns in how you feel, recognizing that productivity and well-being are connected. Its design leans toward being supportive rather than demanding, with smart features that help surface what to work on without piling on pressure, which makes it feel more forgiving than many productivity tools.

Lunatask's emphasis on privacy is a key differentiator: your data is end-to-end encrypted, so your tasks, notes and personal tracking stay private. This, combined with its all-in-one nature and gentle approach, makes it appealing to people who want a single tool for organizing their life and mind, who value privacy, and who appreciate software designed with mental well-being in mind. As more people look for productivity tools that are both capable and kind — and that keep their personal data private — apps like Lunatask fill a meaningful niche. For anyone seeking a private, all-in-one place to manage their tasks, notes, habits and mood with a supportive, thoughtful approach, Lunatask offers a distinctive and genuinely caring solution.
