Why Cash Dollar Tools?
Many free online tools work by uploading your file to a remote server. That is slow, and it means your invoices, contracts and personal photos are copied somewhere you cannot see. We build our tools so that the work happens in your browser instead.
We also try to be straightforward about what each tool can and cannot do. Where a browser cannot do something reliably, such as true PDF encryption, we say so and point you to a safer method. Learn more on our About page and in our Editorial Policy.
Frequently asked questions
Are the tools really free?
Yes. Every tool is free to use without registration. The site is supported by advertising.
Are my files uploaded to your servers?
For almost all tools, no. Files are processed in your browser on your own device. A few tools load libraries or data (for example OCR language data or live exchange rates) from public services, but your files are not sent.
Do the tools work on a phone?
Most do. Heavy tasks such as video processing work best on a computer with a recent browser.
Why do some tools take time?
Browser-based processing uses your device, so large files take longer. Video tools re-encode in real time.
Will you add more tools?
Yes. Tell us what you need through the contact page.
Can I trust the results?
We describe the limits of each tool on its page. Check important output before relying on it, and keep your originals.
