A toolbox that does not get in your way
Most online converters ask you to upload a file to a server you know nothing about, wait in a queue, watch an ad, and then hand back a watermarked result. ToolsBay works the other way around. Every tool here is a small program that runs inside the page you are already looking at, using your own processor. There is no upload step because there is nowhere to upload to.
That design has a practical consequence worth knowing: because the work happens locally, very large files are limited by your device's memory rather than by a plan tier, and a scanned PDF with no text layer cannot be converted to text by any client-side tool, ours included. Where a tool has real limits, its page says so plainly instead of failing silently.
What you can do here
The PDF tools move documents between PDF, Word, spreadsheets, images and plain text. The image tools convert between JPG, PNG, WebP and the HEIC format iPhones produce. The developer tools cover the formats you actually work in — JSON, YAML, XML, SQL and regular expressions. And the encoding tools handle Base64, URL escaping, JWTs and cryptographic hashes.
If you would rather understand a format before converting it, the guides explain what each one stores and what gets lost in translation.
