CleverUtils vs Miro: 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.

Miro is an online collaborative whiteboard platform that gives teams an infinite visual canvas to brainstorm, plan, and work through ideas together in real time. As remote and hybrid work has made the spontaneous, visual collaboration of a physical whiteboard harder to recreate, Miro fills that gap with a shared digital space where distributed teams can think visually together as if they were in the same room. It has become one of the most widely used tools for visual collaboration, workshops, and any work that benefits from seeing ideas laid out spatially.

On Miro's endless canvas, teams can add sticky notes, diagrams, flowcharts, mind maps, images, documents, and more, arranging and connecting them freely to map out ideas and processes. It supports real-time collaboration so everyone can contribute simultaneously, with templates for common activities like brainstorming, retrospectives, user journey mapping, and planning that help teams get started quickly. Miro integrates with the other tools teams use, supports facilitation features for running effective workshops, and increasingly incorporates AI to help generate and organise content on the board, making collaborative sessions more productive.

Miro is used by product teams, designers, agile teams, educators, and any group that needs to brainstorm, plan, or visualise work together, especially across locations. The value is shared visual thinking: it recreates and even improves on the collaborative whiteboard experience, letting teams ideate, align, and organise complex information together regardless of where they are. For workshops, planning sessions, diagramming, and creative collaboration, Miro provides a flexible, engaging space that keeps everyone literally on the same page. As visual, collaborative work has become essential to how modern teams operate, Miro has established itself as a leading platform for bringing people together around ideas.
