Stellar Online PDF Repair review
A browser-based PDF repair tool with previews and monthly file limits.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Stellar Online PDF Repair is a browser-based service for repairing corrupted PDF files without installing software. It is aimed at solo users and small organizations that want to upload a document, let the service scan and repair it, then preview the result before saving. It supports PDF versions 1.3 through 1.7 and documents created with Adobe Acrobat, WPS Office, MS Office, and other applications. Its web-only workflow suits users who prefer not to install a desktop repair tool.
The plans are defined by monthly repair allowances and file-size limits. Free repairs one corrupt PDF file per month, with a 10 MB limit. Premium is $9.99 per month and raises the allowance to five files per month, with a 25 MB limit per file. Both plans are subscription-based, so the practical choice depends on how often repairs are needed and the size of the documents. Premium adds capacity rather than a different repair workflow; occasional users can start with the free allowance, while recurring needs may call for the paid tier.
The preview step is useful because it lets users inspect repaired content before saving. The service says it can restore elements such as headers, footers, forms, word art, and shapes, though its scope remains file-by-file rather than batch repair. Choose it for a small number of PDF repair jobs where a browser workflow and preview matter. It is a weaker fit for frequent or batch workloads, or files above the applicable size limit; users with those needs should consider a tool whose published limits match their workload.
