Uploading to the National Scholarship Portal? Compress every document to under 200KB first: open PurePDF's free PDF compressor, upload your scanned certificate or marksheet, pick Balanced compression, download the smaller file, and upload that to scholarships.gov.in. It takes under a minute per file — no account, no watermark.
You can fill out a PDF form online for free in under a minute: open PurePDF's free form filler at https://www.purepdf.net/form-filler, upload your PDF, click into each field and type, then download or print the completed form. No account or signup needed. If the PDF has no fillable fields, the same tool lets you type text anywhere on the page.
Yes — you can edit text in a PDF online for free and keep the original font. Upload your PDF to PurePDF's free PDF editor, click the text you want to change, and type — the editor detects the document's embedded fonts and preserves the original typeface, size, and styling automatically. If the PDF uses a font that isn't embedded, match it with a standard equivalent (Helvetica, Arial, or Times New Roman) and your edit will blend in seamlessly.
To convert PNG to PDF free, open https://www.purepdf.net/png-to-pdf, drop in your PNG files, and download the PDF — no signup, no watermarks, batch conversion supported. You can combine multiple PNGs into a single PDF, which is what most form uploads, job portals, and applications expect.
To convert HEIC to PDF free, open https://www.purepdf.net/heic-to-pdf, drop in your HEIC photos, and download the PDF — no signup, no watermarks, batch conversion supported, and files auto-delete after conversion. On iPhone you can also convert from the Files app by saving the photo and choosing PDF export, but an online converter is faster for multiple photos.
To compress a PDF without losing quality, use a "High Quality" or "Balanced" compression level instead of maximum compression — text and fonts are never affected, only images are re-encoded, so most PDFs shrink 40–90% with no visible difference. If a compressed PDF looks blurry, recompress the original with Balanced instead of Extreme.
To convert a scanned PDF to Word, you must run OCR first — a scanned PDF contains images, not text. Upload your scan to PurePDF's PDF to Word tool (https://www.purepdf.net/pdf-to-word), enable the OCR option in the workspace, and download an editable .docx. It's free with no account.
Your ABHA card (Ayushman Bharat Health Account) downloads as a PDF. Portals and hospital desks often cap uploads at 300KB — compress it free with PurePDF's online PDF compressor (no signup), keep the final file around 250–300KB, and verify the QR code stays sharp before uploading.
The e-Aadhaar PDF password is the first 4 letters of your name in CAPITAL letters (exactly as printed on your Aadhaar card) followed by your 4-digit year of birth — for example, RAHU1992. Enter it when your PDF reader prompts you, and the file opens instantly.
To compare two PDF files, upload both to a PDF comparison tool, which renders them side by side and highlights every added, removed, or changed word. PurePDF's free Compare tool does this entirely in your browser — your files are never uploaded — and lets you download the comparison as a PDF report.
Upload your PDF to PurePDF's free AI summarizer at purepdf.net/summarize-pdf, pick a brief, detailed, or bullet-point summary, and get the key points in seconds — no signup, no cost, works in 50+ languages.
Upload your bank statement PDF to a free PDF-to-Excel converter, download the spreadsheet, and fix column alignment in Excel. If your statement is password-protected (common with Indian bank e-statements), unlock it first — then conversion takes under a minute.
Upload your PDF to PurePDF's free Protect PDF tool, set a strong open (user) password, choose 256-bit AES encryption, and download the locked file. Send the password to the recipient through a separate channel from the file itself.
Upload your scanned PDF to Google Drive, right-click it, choose Open with > Google Docs — Drive runs OCR and opens an editable text version. It's free but drops most formatting and needs a Google account; for a searchable PDF with layout preserved, use PurePDF's free OCR tool instead.
You've got five PDFs on your phone — a resume, a cover letter, certificates, an ID scan — and the job portal (or government site) accepts exactly one upload. On a laptop this is a 30-second job. On a phone, it used to mean emailing yourself files and borrowing a computer. It doesn't have to. You can merge PDFs directly on your iPhone or Android in under a minute, free, with nothing to install and no account to create. Here's how.
To compress a PDF online free, upload it to PurePDF's Compress PDF tool, pick a compression level, and download the smaller file. Most PDFs shrink 40–90% with no visible quality loss, right in your browser — no signup or watermark.
OCR (optical character recognition) converts images of text into real, searchable text. Applied to a scanned PDF it creates a searchable PDF: Ctrl+F works, text is selectable and copyable, and conversions to Word keep paragraphs and tables instead of images.
To scan documents to PDF for free, use your phone's built-in scanner — the Notes app on iPhone or Google Drive's Scan on Android — to capture each page and save it as a PDF. Or upload your photos/scans to PurePDF's free Scan to PDF tool (https://www.purepdf.net/scan-to-pdf) to combine them into one searchable PDF with OCR — no signup, no watermark.
The fastest free way to convert a PPT to PDF is an online converter like PurePDF's PPT to PDF tool: upload your PowerPoint file, click convert, and download the PDF — no signup, no software, and layouts, fonts, and images are preserved.
Upload your PDF to a free page-number tool, choose where the numbers go, pick a format like "Page 1 of 10", and download — PurePDF stamps them onto every page in seconds, no signup needed.

To create a PDF signature, open your PDF in a free online signer like PurePDF's Sign PDF tool (https://www.purepdf.net/sign-pdf), draw, type, or upload your signature, place it where you need it on the page, and download the signed PDF. No downloads, no account, and no watermark.

Open https://www.purepdf.net/remove-pages, upload your PDF, click the page thumbnails (or type ranges like 2, 5-8) to mark the pages you want gone, then export the cleaned file. It is free, needs no account, adds no watermark, and runs entirely in your browser so the file never leaves your device.
