Nepali text edits (Devanagari)
Runs entirely in your browser. Files never leave your device.
Workspace
Add PDFs or images below — everything lands in one shared page workspace. Reorder by dragging, mix pages from multiple files to merge, insert blank pages, split ranges (or every page) into separate files, then export with optional watermark, page numbers, and metadata all in one pass.
Drop PDFs or images here, or click to browse
Add as many files as you like — PDF pages and images (JPG/PNG) all become pages in this one workspace
SelectOrganizeMergeadd more files above — they append to this workspace0 pages
Workspace is empty
No pages loaded yet — add a PDF or image above to get started.
Split into separate files
Give page ranges (using the numbering shown on each thumbnail above), or split every page out on its own. Downloads as one .zip.
Export
Applies to all pages in the workspace, or just the ones you've selected above.
Edit Page
Add typed text, cover mistakes with a whiteout box, or highlight sections directly on a page, then export a new PDF with those edits baked in. Typed text auto-detects Nepali (Devanagari) and embeds a real font for it, so it renders correctly — not just Latin. Complex conjuncts may still look slightly different from your source font, since this uses one standard Devanagari typeface rather than matching the original.

Select: click an edit below to remove it. Add text: click the page, type, Enter — ink colour auto-matches what's under your cursor. Cover/erase: drag a box — it samples nearby paper colour so it blends in rather than showing a white patch. Highlight: pick a colour, then drag a box. Signature: draw or type it below, then drag on the page to place it. Rotate before adding edits on a page for correct alignment.

Extract Text — font aware
Pulls the exact characters stored in the PDF's text layer and tells you which font rendered each run. Text typed in Preeti is automatically converted to readable Unicode Devanagari in the right-hand column — raw and converted shown side by side so nothing is hidden or guessed silently. Other legacy fonts (Kantipur, Kalimati, etc.) are flagged but not yet auto-converted. If a PDF has no text layer at all (a scan or photo), use OCR below instead.

OCR — for scanned pages
Reads text out of scanned/photographed pages using on-device recognition (nothing uploaded). Works best on clear, upright, reasonably high-resolution scans — accuracy on messy handwriting or low-quality photos will be lower, so proofread the result. First run downloads a small language file and takes a bit longer.
Password & Compress
Add or remove a password, and shrink file size. Everything happens on your device — a password never leaves your browser.
Add a password
Encrypts the PDF so it asks for this password when opened (AES-128). Uses the same encryption approach as most password-protect tools.
Drop a PDF here, or click to browse
One file at a time
Remove a password
Opens a password-protected PDF with the password you provide, then rebuilds it without protection. Note: this rebuilds each page as an image to guarantee it works regardless of how the file was encrypted — the output won't have selectable/searchable text. If you need the text kept, send me the file and password directly instead.

Enhance
Clean up an entire scanned PDF in one pass — brightness, contrast, sharpness, and black & white — instead of adjusting page by page. For fine control on individual pages, use Edit Page instead; this is the one-click, whole-document version.

Sathi Date Convertercompanysathi.com
Convert between Bikram Sambat (Nepali) and Gregorian (English) dates, both directions. Covers BS 2000–2099 (roughly AD 1943–2043).
Nepali (BS) → English (AD)
English (AD) → Nepali (BS)
Accuracy note: Nepali calendar month lengths don't follow a fixed formula — they're set year by year. This tool uses a lookup table cross-checked against multiple independent public calendar sources (including several New Year and festival transitions from 2077–2083 BS). For anything legally critical, it's worth a quick cross-check against an official Nepali calendar (patro) too.

Type phonetically on the left in plain English letters and it converts live into both Unicode and Preeti. Or skip straight to either box on the right — Preeti and Unicode convert live, both directions, and each box stays independently editable so a manual fix never gets silently overwritten.

standard Devanagari
Roman typing cheat sheet — double a vowel for the long form (a→अ, aa→आ, i→इ, ii/ee→ई, u→उ, oo→ऊ). Aspirated consonants: kh, gh, chh, jh, th, dh, ph, bh. Retroflex sounds (rarer, mostly loanwords) use a "2": t2, d2, n2, sh2 → ट, ड, ण, ष. "x" is a shortcut for छ. ksha/gya are typed whole for क्ष/ज्ञ. Case doesn't matter — "Nepal" and "nepal" convert the same way.
namaste → नमस्ते
ke chha hajur → के छ हजुर
kasto chha → कस्तो छ
mero naam → मेरो नाम
timro ghar → तिम्रो घर
chhot2o → छोटो
Kantipur & Kalimati are visible as selectable font options above so the interface is ready for them, but they stay locked for now. I looked for a character-mapping table I could verify the way I checked Preeti (against known reference conversions) and didn't find one I trust — shipping a guessed Devanagari mapping for your documents would be worse than not having it. Send a short Kantipur or Kalimati sample together with its correct Unicode text and I'll build and verify a real mapping, the same way, then unlock it here.

Spreadsheets
Convert between Excel and plain-text tabular formats, or export a sheet as a real PDF or a JPG image.
Drop an .xlsx, .xls, .csv, or .tsv file here, or click to browse
Converts both ways — spreadsheet to text, or text to spreadsheet — plus PDF and JPG export
Word Documents
Drop a .docx to extract clean text and HTML, or generate a real downloadable PDF from it directly — no print dialog. This reads real paragraphs, headings, and lists, but complex layouts (tables, columns, image-heavy pages) won't be pixel-perfect. For a faithful docx → PDF with your exact formatting, hand me the file directly.
Drop a .docx file here, or click to browse
Legacy .doc files aren't readable by browser tools — send those directly and I'll convert them
PDF → Word / Excel
Pulls the text layer out of a PDF and rebuilds it as a real, editable .docx or .xlsx. Works well on text-based PDFs (reports, letters, exported statements). Scanned/photographed PDFs have no text layer to pull from — send those to me directly and I'll run OCR first. Table detection for Excel is a best-effort layout guess, not a guarantee — proofread the result.

.rar files: RAR uses a proprietary, closed compression format — there's no reliable open-source way to create or fully extract them in a browser. Send me a .rar directly and I'll handle it with proper tools instead.
PowerPoint & everything else
Some conversions genuinely need more than a browser trick to come out right — building PowerPoint decks, high-fidelity docx → PDF with your exact formatting preserved, or OCR on scanned documents. I have proper tools for all of these; they just work best when you hand me the file directly in chat.
Just send me the file
Drop it in our chat and tell me what you need. I can handle, with real fidelity:
• Word → PDF, with your exact fonts, headers, and page layout preserved
• PowerPoint creation or conversion — decks built from scratch, or PPTX → PDF
• Scanned documents — OCR to pull text out of a scan or photo
• Complex PDF tables that the browser-based Excel extraction gets wrong
• .rar archives and other formats a browser can't safely handle
About .exe files: an .exe is a compiled program, not a document — there isn't a meaningful way to "convert" a PDF or spreadsheet into a program, or a program into a document; the two aren't different formats of the same content, they're fundamentally different kinds of things. If what you actually need is to package a script or tool as a Windows executable, that's a real, specific task — tell me more about what you're trying to do and I can help with that directly instead.
