Online-Spellcheck.com
Verified working Sep 21, 2026
A browser-based checker for pasted text, files, URLs, and images.
Online-Spellcheck.com is a free web tool for checking spelling and grammar in text, documents, web pages, and uploaded files. It supports many languages and accepts several input methods, including pasted text, URLs, local files, cloud imports, and images converted with OCR.
Why it stands out
- Handles more input types than a basic paste-in spell checker, including URLs, cloud files, and images.
- Covers a broad set of languages and regional variants, not just English.
- Combines dictionary matching, rule-based grammar checks, and statistical error detection according to the site.
- Lets registered users mark false positives and reuse those choices in later checks.
Good to know
- Automated proofreading will not catch every issue; the site itself notes that human review is still the final safeguard.
- Personal dictionary features require registering an account.
- Uploaded, cloud, and URL-submitted documents are processed on the service’s servers, which may matter for sensitive text.
Under the radar: If proper nouns or specialist terms keep getting flagged, log in before marking them correct so the choice is saved to your personal dictionary for future checks.
