Flat / PPT hosting
PPT hosting: upload legacy PowerPoint slides and share a link
Share an existing PPT deck without asking every reader to open it in PowerPoint. Publish from your browser or the CLI for a PDF reading preview and an original-file download.

Flat converts supported PPT files into PDF pages for its browser viewer. The screenshot shows a real conversion of the sample legacy PowerPoint deck.
Old fonts, embedded objects, and presentation effects can change or disappear in the PDF. The preview is a static reading copy. The original PPT remains available for the desktop application that supports it.
A single file opens in the viewer. Several files open in the explorer, where readers can choose a file. Public links need no Flat account. Original downloads remain available if a preview cannot load.
The main link opens Flat's viewer. The exact path /project-brief.ppt serves the original file, without changing its contents.
How to upload PPT files and get a link
Prepare your file
Open the legacy deck in compatible presentation software and check it before publishing. Save a valid PPT file; renaming a PPTX file does not produce the older binary format.
Replace missing linked images and check old fonts. If you are revising the deck for current software, export a PPTX version in your editor and verify the conversion before uploading it.
Publish from your browser or terminal
In your browserGo to uploaderDrop, publish, copy the link.
Drop your finished files into the uploader above, or select them from your device. Enter your email if signed out, then choose "Publish files".
Selected files need unique names and publish at the top level. Use the CLI for folders; the browser uploader does not accept folders or extract ZIPs.
TerminalNode.js 20+One command. Files or folders.
npx -y @getflat/cli deploy ./project-brief.pptReplace the example path with your file. Pass a folder to publish related files with their relative paths intact. The CLI prints the published URL.
Check before sharing
Compare the PDF pages with the original deck. Check text wrapping and old diagrams, then download the PPT to confirm the source remains usable.
Signed-out uploads expire after 1 hour by default. Sign in before expiry to keep them online, or sign in before publishing for no default expiry.
What you can share with PPT hosting
Training archives
Make an older course deck readable through a link while keeping the PPT available for reuse in compatible software.
Legacy slide handoffs
Give a recipient a static preview of an existing deck before they download the original for a migration or redesign.
Keep a version, or keep an address.
Share this version
Every upload gets its own link. Publishing revised files creates a new link and leaves the earlier version unchanged. Use the version link when someone needs to review a specific upload.
Update files at one address
Use a named onflat.page address or your own domain. Sign in, then publish with the CLI using --domain. Publish revised files with the same domain to point that address to the new upload.
Named addresses are included on Free. Adding your own domain requires a paid plan. The browser uploader does not set up or repoint these addresses.
PPT hosting questions
Is hosting free, and what are the limits?
Yes. Signed-in Free includes 5 MiB per upload, 1 GiB of storage, and 5 GiB of monthly transfer, with no default expiry. The per-upload limit covers all files in that upload. Paid plans raise these limits.
Do readers need a Flat account?
No. Public links open without a Flat account. Anyone with the link can open the uploaded files. Password-protected links also require the visitor password.
Can I password-protect my upload?
Yes. Password protection is available on every plan. Add --password YOUR_PASSWORD to your CLI deploy command. It protects access to the upload and its files, but does not prevent someone with access from saving a copy. The browser uploader creates public uploads.
Can I replace files without changing the link?
A version link always refers to its original upload. For same-address updates, use a named address or your own domain. Publish revised files with the same --domain value in the CLI to point that address to the new upload.
What happens when an upload expires?
Flat stops serving it. An expired upload cannot be recovered. Signed-out uploads expire after 1 hour by default. For browser uploads, use the sign-in link shown after publishing. For CLI uploads, run npx -y @getflat/cli login. Complete sign-in before expiry to keep the upload online. If you chose a shorter expiry in the CLI, that deadline stays in place.
Does hosting turn my PPT into PPTX?
No. Flat generates a PDF reading preview and preserves the original PPT. Use a presentation editor to create a PPTX copy if your recipient needs the newer format.
What if the old deck does not convert correctly?
The original remains available to download. Open it in compatible software, resolve missing fonts or objects, and export your own PDF reading copy. Check that PDF before publishing it.
How large can an upload be?
Upload allowances depend on your plan and cover all files in the upload. Compare current plan limits. Preview availability also depends on format and processing support. The original file remains available to download if a preview is unavailable.
Can I embed the viewer on another website?
Flat's generated viewer cannot be embedded in an iframe and keeps Flat branding on every plan. Link to the viewer for reading or to the exact file URL for the original.
