Facebook Upload Error Won't Go Away? Here's What's Actually Causing It and How to Fix It

A Facebook upload error occurs when the platform cannot process a photo, video, or file you're trying to share — either due to format restrictions, file size limits, network issues, browser incompatibilities, or a temporary server problem on Facebook's end. Identifying the specific cause is the fastest path to fixing it.

Part 1. Common Causes of Facebook Upload Errors

Upload errors on Facebook are rarely caused by a single issue. Understanding the range of possible causes helps avoid trying fixes that don't apply to your situation.

🗣️ r/facebook user: "Spent an hour thinking it was my file. Turns out Facebook was having a partial outage affecting video uploads. Checked Downdetector and there were hundreds of reports."

Checking Downdetector for Facebook before spending time on local fixes can save significant troubleshooting effort.

Part 2. Facebook's File Format and Size Requirements

Before troubleshooting the upload process itself, verify that your file meets Facebook's technical specifications.

Photo requirements:

• Supported formats: JPG, PNG, GIF, BMP, TIFF, WEBP
• Maximum file size: 8 MB per photo
• Maximum resolution: 2048 × 2048 pixels for standard posts (higher for albums)
• Recommended: JPG or PNG under 5 MB for fastest upload

Video requirements:

• Supported formats: MP4 (recommended), MOV, AVI, FLV, MKV, WMV, MPEG, and more
• Maximum file size: 4 GB
• Maximum length: 240 minutes
• Recommended resolution: 1080p or lower for fastest processing
• Recommended codecs: H.264 video, AAC audio

💡 Tip: HEIC photos taken on an iPhone may fail to upload on some browsers. Convert them to JPG using the iPhone's built-in export option or a free converter before uploading to Facebook.

Part 3. Fix Facebook Upload Error on Mobile

Mobile upload errors often stem from the app state, network, or permissions rather than the file itself.

Step 1 — Check your internet connection Switch between Wi-Fi and mobile data to test whether the error is network-related. Large video uploads in particular may time out on weak Wi-Fi signals.

Step 2 — Force-quit and reopen the Facebook app On iOS, swipe up from the bottom and swipe the Facebook app card away. On Android, use the recent apps button and close Facebook. Reopen and try again.

Step 3 — Update the Facebook app An outdated app may have upload bugs that were patched in a newer version. Check the App Store or Google Play for a pending update.

Step 4 — Clear app cache (Android) Go to Settings → Apps → Facebook → Storage → Clear Cache. This removes stale data that can block upload API calls. Note: this option is not available on iOS; delete and reinstall the app instead.

Step 5 — Check app permissions Ensure Facebook has permission to access your Photos and Storage. On iOS: Settings → Facebook → Photos → set to "All Photos." On Android: Settings → Apps → Facebook → Permissions → Allow Photos/Media.

⚠️ Important: Do not delete the Facebook app before saving drafts of any long posts or stories you were working on. The app deletion does not affect your account or data on Facebook's servers, but any locally unsaved drafts will be lost.

Part 4. Fix Facebook Upload Error in a Browser

Browser-based uploads fail for different reasons than mobile. These are the most effective fixes.

Step 1 — Try a different browser Open Facebook.com in an incognito window or switch to a different browser (Chrome, Firefox, Edge). This isolates whether the issue is browser-specific.

Step 2 — Disable browser extensions Ad blockers, privacy extensions, and script blockers can interfere with Facebook's upload API. Disable all extensions temporarily, then retry the upload.

Step 3 — Clear browser cache and cookies In Chrome: Settings → Privacy and security → Clear browsing data → Select "Cached images and files" and "Cookies" → Clear data. Then log back into Facebook and retry.

Step 4 — Check file path for special characters Rename the file to remove spaces, accents, or symbols before uploading. Use simple names like vacation_video.mp4 instead of filenames with parentheses or non-ASCII characters.

🗣️ r/techsupport user: "My video had an apostrophe in the filename. Renamed it to something plain and it uploaded instantly. Facebook's uploader doesn't handle special characters well."

Part 5. Convert or Compress the File Before Uploading

If the file format or size is the issue, converting or compressing it before upload typically resolves the error.

Convert HEIC to JPG (iPhone photos): On iPhone, go to Settings → Camera → Formats → Select "Most Compatible." Future photos will be saved as JPG. For existing HEIC files, use iMazing HEIC Converter (free, Windows and Mac) to batch-convert.

Compress large videos:

• On Mac: use HandBrake (free) to re-encode to H.264 MP4
• On Windows: use VLC Media Player or HandBrake
• On iPhone: use the built-in "Low" or "Medium" quality setting in the Photos sharing sheet
• Online: Clideo or Kapwing for quick browser-based compression

💡 Tip: Facebook recommends H.264 MP4 at 1080p or lower for the best upload reliability and playback quality. Encoding above 1080p typically provides no visible quality improvement on Facebook while dramatically increasing upload time and failure risk.

Part 6. Recover Lost Media Files With Ritridata

If you accidentally deleted photos or videos from your computer, SD card, or external drive while trying to fix the upload error — or lost files during a device reset — Ritridata can help recover them.

Ritridata scans HDDs, SSDs, SD cards, USB drives, and external drives on Windows and Mac to find and restore deleted photo and video files including JPG, PNG, MP4, MOV, and many other formats.

Step 1 — Select the drive/location

Step 2 — Run a safe scan

Step 3 — Preview and recover to another drive

FAQ

Q: Why does my Facebook video upload keep failing at the same percentage? A: A stalled upload at a specific percentage usually points to a network interruption. Try uploading on a more stable connection, or use the Facebook mobile app on LTE rather than Wi-Fi if your Wi-Fi is inconsistent.

Q: Does Facebook support HEIC photos directly? A: In most cases, no. HEIC uploads may work on some Facebook app versions on iOS, but browser-based uploads typically fail or silently convert. Converting to JPG before upload is the safest approach.

Q: Why does my video say "processing" for hours on Facebook? A: Facebook processes video after upload — this is normal. Long 4K videos can take 30 minutes or more. If it shows "processing" for over 4 hours, the upload may have corrupted mid-transfer; delete it and upload again.

Q: Can I upload directly from iCloud Photos to Facebook? A: This depends on your browser and iCloud settings. On Safari with iCloud Photos enabled, you can select iCloud-stored photos. On Chrome or other browsers, you may need to download the photo locally first.

Q: Does Facebook have an upload limit per day? A: Facebook doesn't publish a hard per-day upload limit for individual accounts. However, uploading a very large number of files in a short period may trigger spam detection, temporarily restricting uploads.

Q: Why does the video upload work on mobile but not in the browser? A: Mobile apps use a different upload API than the browser. Browser uploads depend on the file upload API which can be affected by extensions, network proxies, or browser sandbox restrictions. Trying an incognito window removes most browser variables.

Q: What should I do if none of the fixes work? A: Check Downdetector for a reported Facebook outage. If there's no outage, contact Facebook support through the Help Center and report the specific error message you're seeing.
