Kompresor GzipGzip text and download the .gz or inspect Base64.Dekompresor GzipInflate gzip payloads from files or Base64.Kompresor DeflateRaw DEFLATE compression in the browser.Dekompresor DeflateInflate raw DEFLATE data.Kompresor BrotliCompress text with Brotli (RFC 7932) directly in your browser — the same codec Google ships, compiled to WebAssembly, quality 0–11, Base64 or Hex output with exact size statistics.Dekompresor BrotliPaste Base64 or Hex brotli data and get the original text back — real RFC 7932 decompression in WebAssembly, binary payloads detected and re-encoded, nothing uploaded.Bzip2 CompressBzip2 is a compression library developed by Julian Seward (of GHC fame) that uses the Burrows-Wheeler algorithm. It only supports compressing single files and its compression is slow, however is more effective than Deflate (.gz & .zip).

Password-protected PDFs are not supported.pembalikan PDF PagesFlip a PDF end to end — the last page becomes page 1 and vice versa, no page content is re-encoded, and the whole reorder runs locally in your browser with no upload and no sign-up.Konverter PDF to teksConvert a PDF to text in your browser — every page is parsed locally with pdf.js, lines come out in reading order, and you get word and character counts plus a .txt download. No upload, no sign-up; scans (no OCR) and password-protected files are declined, and layout is not preserved.Extract teks from PDFExtract the text out of a PDF in one tab: click or drop your file and pdf.js pulls every selectable line locally — the document itself never leaves your machine. Per-page failures degrade to a placeholder instead of killing the run.Pengekstrak PDF teksA local PDF text extractor: open the file with the pdf.js engine right in this page, copy the plain text or download it as .txt, with page/word/character counts shown up front.
