CloudConvert is a long-standing online conversion service that handles hundreds of formats. For exotic conversions (DOCX to PDF, AI to SVG, HEIC to JPG) it's a great fit. For the everyday image formats most people actually need — JPG, PNG, WebP — it's slower, less private, and unnecessarily heavyweight compared to a client-side tool like Pixnova.
How CloudConvert works
You upload your file to CloudConvert's servers in Germany. Their conversion farm processes the file. The result is stored on their servers for 24 hours, then you download it back to your device. The free tier limits you to 25 conversions per day and 1 GB of total file size.
It's a fine architecture — but it means every file you convert is briefly stored on a third-party server, your network has to upload and re-download the file, and you're rate-limited.
How Pixnova works
Pixnova converts JPG, PNG, and WebP entirely inside your browser using HTML5 canvas. No upload, no server queue, no download — the result is generated locally and saved with a single click. There's no rate limit because there's no server doing the work.
Head-to-head for image formats
- Time to convert a 4 MB JPG to PNG — CloudConvert: 15-40 seconds (upload + process + download). Pixnova: under 1 second.
- Daily limit — CloudConvert: 25/day on free tier. Pixnova: unlimited.
- Where the file lives — CloudConvert: their German servers for 24 hours. Pixnova: your device only.
- Works offline — CloudConvert: no. Pixnova: yes (after first page load).
- Account required — CloudConvert: free tier no, higher tiers yes. Pixnova: never.
When CloudConvert is the better tool
CloudConvert genuinely shines for rare or document-heavy formats: PSD, AI, EPS, DOCX, XLSX, PPTX, MP4 to GIF, audio formats, video formats. If you need to convert a PowerPoint to PDF or an Illustrator file to SVG, CloudConvert is one of the best free options around.
When Pixnova is the better tool
For the conversions that make up 95% of everyday image work — JPG, PNG, WebP — Pixnova is faster, private by design, and never rate-limits you. You also get extras CloudConvert doesn't have: AI background removal, watermark removal, and an interactive compressor.
The TL;DR
If your file is an image and the format is JPG, PNG, or WebP, Pixnova will do the job in your browser before CloudConvert finishes uploading. Try the converter — it's free, unlimited, and your image stays on your device.
