IstaConvert

IstaConvert is a complete file toolkit with 83 tools that run entirely on your device. Compress images to an exact KB (perfect for SSC / UPSC / NEET / JEE / IBPS / passport / visa uploads), resize photos to exact pixels, remove EXIF metadata, convert HEIC to JPG, and batch-process dozens at once. Merge and split PDFs, add page numbers, crop margins, extract text, OCR scanned pages, unlock owner restrictions, remove open passwords, and convert HTML / Word / Excel / Markdown to PDF. Trim, crop, rotate, and compress videos for WhatsApp / email / social, change aspect ratios for reels and TikToks, extract frames, add audio, or convert to and from GIF. Generate QR codes for text, URLs, Wi-Fi networks (guests join with one scan), and UPI payments (GPay / PhonePe / Paytm compatible). Format JSON, XML and CSV. Compare two documents. Test regex. Convert case, timestamps, and colours. Decode JWT tokens. Generate strong passwords, UUIDs, and SHA hashes. Every file stays on your device — nothing is uploaded, nothing tracked, no signup, no watermarks.
