Viewer Issues

Last updated: 2026-03-23

Document viewer issues are typically caused by files still processing, rendering delays with large files, or browser compatibility. This guide covers the most common viewing problems and their fixes.

Document viewer shows blank or won't load

If a document opens but the viewer shows a blank area, work through these steps:

  • Check processing status. Open the document browser and look for the processing indicator next to the file. If it's still processing, the viewer can't display it yet. Wait for processing to finish.
  • Close and reopen the file. Close the viewer tab and reopen the file from the document browser. This forces a fresh load of the rendition.
  • Refresh the page. A full page refresh clears cached state that may be causing the blank display.
  • Check your browser. Hintyr works best in up-to-date versions of Chrome, Edge, Firefox, and Safari. If you're on an older version, try updating.

Slow document loading in the viewer

Large files, particularly PDFs with 100+ pages, may take a few seconds to fully render. This is expected, not a bug. The viewer loads pages progressively, so you can start reading the first pages while the rest load in the background.

If loading times are consistently long for all files, check your internet speed. The viewer streams content from the server, so a slow connection means slower rendering across all documents.

Viewer displays the wrong document

In rare cases, the viewer may show content that doesn't match the selected file. This can happen when the browser has cached a previous document session. To fix it:

  • Close and reopen the file. Select the correct file from the document browser to start a fresh session.
  • Clear browser cache. If the problem persists, clear your browser cache and reload.
  • Re-upload the file. If the content still looks wrong after clearing cache, the file may have hit a processing error. Delete and re-upload it to trigger fresh processing.

Frequently asked questions

Which browsers are supported?
Hintyr supports the latest versions of Chrome, Edge, Firefox, and Safari. For the best experience, use an up-to-date version of Chrome or Edge.
Can I view documents on mobile devices?
Hintyr is optimized for desktop browsers. While the viewer may load on mobile devices, the full review workflow is designed for desktop use.
Why do some pages appear blurry at first?
The viewer loads a low-resolution preview first for speed, then replaces it with the full-resolution page. Wait a moment for the sharp version to render.
