The site was rebuilt. The job is unchanged: upload a file, read it, close it, no account. What follows is what is on it now and what each part accepts, because the question people actually arrive with is "will it take my file".

Converters, and the limit that catches people
A converter accepts less than the viewer for the same format, sometimes much less. Converting rewrites the document; viewing only draws it.
| Converter | In | Out | Limit |
|---|---|---|---|
| Word, DOC, Excel, PowerPoint, PNG, JPG | 25 MB | ||
| Word | doc, docx | PDF, JPG, PNG | 15 MB |
| Excel | xls, xlsx | PDF, JPG, PNG | 5 MB |
| PowerPoint | ppt, pptx | PDF, JPG, PNG | 20 MB |
| Image | png, jpg, jpeg | PDF, WebP, TIFF | 25 MB |
| CAD | dwg, dxf | PDF, JPG, PNG | 5 MB |
| msg, eml | PDF, HTML | 10 MB |
Excel is the widest gap and the one that surprises people: the Excel viewer takes 20 MB, Excel to PDF takes 5. CAD is the same shape — 10 MB to look at a drawing, 5 MB to turn it into a PDF.
Converters also take fewer extensions. The Word viewer opens nine; the Word converter
takes two. ODT, RTF and the template variants have to be saved as .docx first.
Over the limit
Usually images. In Word, Excel or PowerPoint: click a picture, Picture Format, Compress Pictures, tick "delete cropped areas", pick 150 ppi, save under a new name. For a spreadsheet, Ctrl+End shows where the used range really ends — delete the empty rows below it and save again.
What did not change
No account, no sign-up. One file at a time. The file is deleted after viewing, and the rendering engine underneath is the Doconut .NET library.
