TIFF hosting: upload scans and share original files

Upload TIFF scans and print assets from your browser or the CLI. Share the original download, with a separate web-friendly preview when readers need one.

What people see at your TIFF link

TIFF support is limited across browsers. The screenshot shows the actual Chromium fallback: the image cannot be decoded, but the original remains available to open or download.

Flat recognizes TIFF files without converting them into web images. Publish a JPEG or PNG companion for browser review. The explorer lets readers choose that preview or download the TIFF source.

A single image opens in Flat's viewer. Several files open in the explorer. Public links need no Flat account, and original downloads stay available.

The exact path /color-guide.tiff serves the original image. Use the main link for the viewer, or the exact image URL when embedding a browser-compatible image on your website.

How to upload TIFF files and get a URL

  1. Prepare your images

    Keep the original TIFF when a recipient needs its resolution, color data, or multiple pages. Check file size against your plan before uploading. A compressed TIFF can still be too large for the built-in preview.

    Export a PNG preview for a single image. For multipage scans, consider a PDF companion. Flat's image viewer does not provide TIFF page navigation.

  2. Publish from your browser or terminal

    In your browser

    Drop, publish, copy the link.

    Drop your finished images into the uploader above, or choose them from your device. Enter your email if signed out, then choose "Publish images".

    Each file needs a unique name. Selected files 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 ./color-guide.tiff

    Replace the example path with your file, or pass a folder path to publish several images. The CLI preserves relative paths and prints the published URL.

  3. Open and share the URL

    Download the published TIFF and open it in the tool your recipient uses. Check any companion preview in the browser before sharing the link.

    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 TIFF hosting

Scans and print handoffs
Send a TIFF scan or prepared print asset as an original-file download. Supply a separate web preview when recipients need to inspect it quickly.
Multipage scan delivery
Share a TIFF containing several scanned pages. Recipients download it for a TIFF-capable application; include a PDF if they need browser page navigation.
Source and preview pairs
Keep a high-resolution original beside a smaller PNG or JPEG. The explorer lets readers choose the preview or the source file.

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.

TIFF 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.

Set a visitor password

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.

Can readers view TIFF files online?

Only if their browser can decode that TIFF. Many browsers cannot. Flat keeps the original available to download; publish a PNG, JPEG, or PDF companion when browser reading is required.

Are .tif and .tiff different formats?

They are two extensions for TIFF. Both follow the same hosting workflow. Renaming either to PNG or JPEG does not convert its contents.

Does Flat preserve the original image data?

Yes. The uploaded bytes stay unchanged, including the file's embedded data. The viewer is not a color-proofing, layer-editing, or multipage TIFF tool.

Will a paid plan make a large TIFF preview work?

A paid plan can raise the upload allowance, but the viewer still has its own size limit and relies on browser decoding. For a large source file, provide a smaller browser-compatible preview separately.

How large can an image preview be?

Flat's viewer accepts image files up to 5 MiB. The browser must also be able to decode the image. Paid plans allow larger uploads, but do not raise the viewer's preview limit. Original files remain available to open or download when a preview is unavailable.
