Compress, resize, crop to square, convert to PNG/JPG, and optionally limit file size (e.g. 200 KB). All processing stays in your browser.
Tip: Square presets (500×500 etc.) auto center-crop to exact pixels. For exact custom size: set Width + Height, enable Center crop (or turn off “Keep aspect ratio”). Max KB forces smaller file size.
Convert JPG, PNG and WEBP images into one PDF. Preview pages first, then Save / Download, Share or Print.
Upload one or more images of tables, marksheets, invoices or handwritten lists. OCR extracts the text and builds a full Excel workbook (one sheet per image). Processing stays in your browser.
Tip: Clear, well-lit photos of printed tables work best. Scanned sheets and high-contrast screenshots give the most complete Excel rows. Complex multi-column layouts may need a quick cleanup in Excel after download.
Upload a photo or scan of printed or handwritten text. OCR extracts the text in your browser — copy, download as .txt, or share. No upload to a server.
Tip: Clear, well-lit photos of printed text work best. Hindi + English mixed pages: choose English + Hindi. Processing stays on your device.
Upload a ZIP that contains images (JPG, PNG, WEBP, GIF). Images are sorted by file name and combined into one PDF. All processing stays in your browser — the ZIP is not uploaded to a server.
Android: file picker mein Files / Downloads se .zip choose karo (Gallery nahi). Agar ZIP list mein na dikhe to “All files” select karo.
Supported inside ZIP: JPG, JPEG, PNG, WEBP, GIF. Other files are skipped. Large ZIPs with many photos may take longer on mobile.
Convert every PDF page to PNG or JPG. Download pages individually or all pages together as a ZIP.
Create a real .docx Word document directly on your device. No Word library is required.
Convert normal or scanned PDFs into an editable Word document. Text PDFs use direct extraction; image/scanned PDFs automatically fall back to OCR.
Compress video in your browser (no upload). Prefers MP4 so it opens in phone Gallery / WhatsApp. If the browser cannot encode MP4, it falls back to WebM.

Calculate the solar panel capacity, battery bank size and suggested inverter size for home or off-grid solar setups.
Estimate only — actual solar sizing also depends on panel type, shading, weather and inverter specs. Consult a solar installer for a final system design. Peak sun hours in most of India are typically 4–6 hours.
Find out how many hours a battery will run a given load — e.g. how long a 200Ah battery lasts on a 1000W inverter load during a power cut.
Typical DoD: LiFePO4 80–90%, Lead-acid / Tubular 50%. Lower DoD increases battery life. Results are estimates — actual runtime depends on temperature, battery age and inverter efficiency.
Free cable size calculator and electrical wire size calculator. Calculates recommended cable cross-section (mm²) using both voltage drop and current carrying capacity (ampacity). Supports single-phase & three-phase, copper & aluminium.
This calculator checks both voltage drop and approximate current-carrying capacity (based on typical PVC insulated cables at ~30°C). Always follow IS 3961 / local electrical code and consult a licensed electrician before installation. Derating may be needed for high temperature, conduit or grouped cables.
