Obsidian Sync failing or your CPU spiking after adding a PDF? Compress your PDF instantly using the tool below — fixes both Standard (5MB) and Plus (200MB) sync errors.
👉 Fix: Compress your file below the required limit using the tool above.
Obsidian Sync failures caused by oversized files often show no clear error — the sync simply stalls or retries in a loop, causing high CPU usage. Compressing the PDF below your plan's limit stops the retry loop. For files that can't be compressed enough, remove them from the vault and store them in iCloud or Dropbox instead.
If the PDF exceeds your plan's limit (5MB on Standard, 200MB on Plus), Obsidian Sync will fail silently or retry in a loop. Compress the PDF below the limit or remove it from the vault and store it externally.Source: Obsidian Help ↗
A file exceeding the Obsidian Sync size limit can cause the sync client to retry the upload continuously, spiking CPU usage. Compress the oversized file or move it out of the synced vault folder.Source: Obsidian Help ↗
Compress your PDF below 5MB (Standard) or 200MB (Plus) using the tool above. If the file can't be compressed enough, remove it from the vault and link to it from iCloud Drive or Dropbox instead.Source: Obsidian Help ↗
Not always. Oversized files often cause silent failures or continuous retry loops rather than a clear error message. High CPU usage after adding a large file is a common symptom.Source: Obsidian Help ↗
Yes. Store the PDF in iCloud Drive, Dropbox, or another cloud service and paste the file link into your Obsidian note. This keeps your vault lightweight and avoids Sync size limits entirely.Source: Obsidian Help ↗
