よくある質問
Does this support all file formats?
Yes. Any file your browser can read: PDF, DOCX, XLSX, PPTX, CSV, ZIP, PNG, MP4 and more. We report size and encodings; we do not change the file format itself.
Is PDF to bytes the same as PDF to Base64?
Bytes is the raw size. Base64 is the wire encoding (~33% larger). This tool shows both, plus hex.
Do you upload my document?
No. Reading stays in your browser.
