🖼️ Image Compressor & PNG Converter — Reduce Size / Crop

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.

📄 JPG & PNG to PDF Converter — Images to PDF

Convert JPG, PNG and WEBP images into one PDF. Preview pages first, then Save / Download, Share or Print.

📊 Image to Excel Converter — Photo / Table to XLSX

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.

📝 Image to Text (OCR) — Extract Text from Photo

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.

📦 ZIP to PDF Converter — Images in ZIP to Multi-page PDF

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.

📝 Text to PDF Converter
📑 PDF to JPG / PNG Converter

Convert every PDF page to PNG or JPG. Download pages individually or all pages together as a ZIP.

📝 Text to Word Converter

Create a real .docx Word document directly on your device. No Word library is required.

📃 PDF to Word Converter

Convert normal or scanned PDFs into an editable Word document. Text PDFs use direct extraction; image/scanned PDFs automatically fall back to OCR.

🎬 Video Compressor — MP4 / WebM

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.

Gallery tip: Choose Auto or MP4. MP4 opens in almost all phone galleries and WhatsApp. WebM is smaller but many Galleries cannot play it.

☀️ Solar Panel Load & Battery Size Calculator

Calculate the solar panel capacity, battery bank size and suggested inverter size for home or off-grid solar setups.

🔋 Battery Type (sets typical DoD)
LiFePO4 / Lithium (80–90%)
Lead-Acid / Tubular (50%)
⚡ System Voltage
12V
24V
48V

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.

🔋 Battery Backup Time Calculator

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.

🔌 Battery Voltage
12V
24V
48V

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.
