Free tools for email, leads and everyday files
Every free tool we build, in one place. Find contacts, check your email setup, and convert subtitles, PDFs, spreadsheets and photos. The file converters run in your browser, so your files are never uploaded.
- 38 free tools
- No signup for the basics
- File converters never upload your files
No tool matches that search. Try a file type like PDF or CSV.
Which free email tool to use, and when
A cold email campaign needs both groups: the right contacts and a domain that inboxes trust.
Before you build a list
Use the company lookup to check an account fits your market, then the email finder or LinkedIn email finder to get the contact.
When a lead comes to you
Run an unknown address through reverse email lookup, or a missed call through reverse phone lookup, to see who it is.
Before your first send
Run the domain health checker, then fix anything it flags with the SPF, DKIM and DMARC generators.
Before every campaign
Verify the list with the email verifier and run your copy through the spam checker. Bounces and trigger words hurt sender reputation fast.
Why our file converters never upload your files
Most online converters send your file to a server, convert it there and keep a copy for a while. Ours do the work inside your browser, using your own device. The file never reaches LeadCanal and nothing is stored, so bank statements, IDs and private emails stay private.
Each converter only opens the file types it is built for, and checks the start of every file to make sure it really is that type.
Yes. The file converters and deliverability tools are free with no signup and no watermark. The lead finder tools give free daily lookups, and sharing your work email raises the limit.
No. Converters such as TXT to SRT, bank statement to Excel and DNG to JPG run entirely in your browser. Files never leave your device and nothing is saved on our servers.
At minimum: the domain health checker for SPF, DKIM and DMARC, the email verifier on your list, and the spam checker on your copy. Since February 2024, Gmail and Yahoo require authentication from bulk senders.
The email, phone and company tools search a data partner database of 690M+ professional profiles and linked company records.
Yes. We set up and monitor cold email infrastructure, including domains, mailboxes, authentication and warm-up, and we build verified lead lists.
