CleverUtils vs Gamma: 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.

Gamma is an AI-powered tool that reinvents how presentations, documents, and webpages get made. Anyone who has spent an afternoon wrestling slides into alignment knows how much time traditional tools waste on formatting rather than ideas. Gamma flips the process: you describe what you want or paste in your content, and its AI generates a polished, well-designed first draft in seconds — complete with sensible layout, visuals, and structure — which you then refine. It's the difference between starting from a blank slide and starting from something that already looks good.

The format itself is modern and flexible. Gamma's documents are built from responsive "cards" that look great on any screen, blending the structure of slides with the flow of a webpage, and they can include text, images, charts, embeds, and interactive elements. You can present them like a deck, share them as a link that works beautifully on mobile, or publish them as a simple website. The AI doesn't just generate the initial draft; it helps throughout, letting you restructure, rewrite, and restyle with prompts, so iterating on a presentation feels conversational rather than manual. Templates and smart design keep everything looking professional without any design skill required.

Gamma is used by founders pitching, marketers building one-pagers, educators creating lessons, sales teams making proposals, and anyone who needs to communicate an idea visually but doesn't want to spend hours in slide software. The core value is speed without ugliness: you get a presentation or document that looks like a designer touched it, in a fraction of the time, with the AI handling the tedious formatting and giving you a strong starting point. For the countless moments when you need to turn an idea into something shareable and good-looking fast, Gamma removes the friction and lets you focus on the message rather than the mechanics.
