Frequently Asked Questions
Does DoctorDocs handle bulk image compression?
Yes. Our image compressor supports batch uploads — drag and drop multiple images and compress them all at once. Output quality is adjustable, and all processing happens in-browser for maximum speed.
Are developer tools really free with no limits?
Yes. All developer utilities are completely free with no per-use limits, no sign-up requirements, and no watermarks. We fund the platform through non-intrusive ads on tool pages.
Do screenshots or files ever leave my browser?
For the client-side tools — image compression, format conversion, hash generation — no. Processing runs locally in JavaScript, so code screenshots, internal docs, and unreleased mockups never touch a server.
Can I format and validate JSON, CSV, and XML locally?
Yes. Our developer data formatters validate syntax, prettify indented trees, and convert between JSON, CSV, and XML completely offline inside your browser sandbox with zero network telemetry or tracking. Additionally, you can parse JWT tokens, encode and decode Base64 strings, calculate cryptographic hashes, and inspect binary headers with zero network calls.
Can I inspect and edit SVG graphics and markdown directly?
Yes. DoctorDocs includes specialized client-side SVG code viewers, Markdown editors with live preview, and CSS formatters that let you tweak web assets instantly without opening heavy IDEs.
