Everyday file conversions without Zamzar's two-files-per-24-hours free ceiling — limited to the formats a browser can decode on its own.
No upload — files are processed in this tab
Convert JPG, PNG, and other image formats to high-quality PDF documents. Drag and drop your images to create professional PDFs instantly.
This is the real tool, not a demo. Open Image to PDF Converter on its own page.
Two files per 24 hours is the tightest free tier in this list, and it is deliberate: Zamzar's catalogue runs past 1,100 formats, and running CAD, 3D and ebook conversions costs them real compute per file. If you need one of those formats, nothing here helps and you should pay them. If you are converting a phone photo to JPG or a set of images into a PDF, those run in your browser instantly and repeatedly, which is what the free-tier counter was standing in the way of.
| Comparison point | AltFTool | Zamzar |
|---|---|---|
| Where the work happens | File tools (PDF, image, converters) run in your browser and the file is not uploaded. Tools that need live data or a model — AI tools, language checkers, lookups — send your input to an API, and say so on their own page. | Uploaded; the original is deleted as soon as it is converted, the output held 24 hours. |
| Account required | No — every tool opens and runs without signing in. | Not needed for the free service. |
| Free tier ceiling | — | 2 conversions and 2 compressions per 24 hours, 50 MB total per upload. |
| Paid plans | None. There is no paid tier and no per-file metering. | Basic US$12/mo, Pro US$19/mo, Business US$39/mo. |
| Ads | Yes — ads are what keep the tools free. | No ads; the free tier is limited by the daily file count. |
| Desktop / mobile apps | No. Web only — no desktop or mobile app. | Yes — desktop conversions, capped at 50–500 per day by plan. |
| API & automation | No public API. Tools are interactive pages, not endpoints. | Yes — a documented conversion API. |
Paid pricing: Basic US$12/month, Pro US$19/month, Business US$39/month
