For the best and most reliable results, we recommend exporting to PDF before uploading. --- **What's the maximum file size?** File size limits depend on your plan — Basic supports up to 75 MB, Pro up to 250 MB, and Business up to 350 MB. --- **Can I change my page flip after converting?** Yes — you can update your page flip at any time after conversion. See [Which Page Flip Should I Choose?](link) if you're not sure which one to go with. --- **Why isn't the Trifold (or Gatefold) option appearing?** These options only appear when your PDF is formatted correctly for that layout. For Trifold, your file must be exactly 2 pages with 3 panels per page. If the option isn't showing up, your PDF likely isn't structured that way — see [Upload a Trifold Brochure](link) for formatting requirements. --- **Can I update my file after uploading?** Yes. Use the **Replace** feature on your Dashboard to swap in a new file. Your link, embed codes, and QR code all stay the same — readers will automatically see the updated version. --- **Can I upload multiple files at once?** No — each Simplebooklet is created from a single file upload. If you want to combine multiple documents, merge them into one PDF first using a tool like [ilovepdf.com](https://www.ilovepdf.com) before uploading. --- **Why does my text look blurry or my layout look off after converting?** This usually happens when a file uses custom fonts that weren't embedded, or when a non-PDF format loses formatting during conversion. Export your file as a PDF before uploading for the cleanest results. If you're uploading from Illustrator, use the **PDF/X-1a:2001** preset. --- **Can I upload from Google Drive or Dropbox?** Not directly. Download your file to your computer first, then upload it from there. --- **What happens during conversion — how long does it take?** Once you upload your file, Simplebooklet processes it and creates a web-ready flipbook with its own landing page. Conversion time depends on file size and your internet speed — most files are ready in under a minute. --- **Can I have more than one Simplebooklet from the same file?** Yes. You can upload the same file multiple times to create separate Simplebooklets — useful if you want different titles, themes, or share settings for the same content. --- **Do I need to use Advanced Settings?** Most of the time, no. Advanced Settings are only needed for specific situations — like bifold PDFs where every page is a landscape double-panel spread. See [Upload a Bifold Brochure](link) for more detail. --- ### Related Articles * [Which Page Flip Should I Choose?](link) * [Upload a Trifold Brochure](link) * [Replace or Update Your Simplebooklet](link)
