Meet OptiSqueeze – a complete on-device Image and PDF toolbox that compresses, converts, merges, splits, locks, and edits your files in seconds, without ever uploading them anywhere.
Hit a 100 KB upload limit, merge scans into one PDF, convert HEIC to JPG, or password-protect a contract – all in one app, with no internet required and no data leaving your phone.
🌟 WHY CHOOSE OPTISQUEEZE?
Most online file tools make you upload private documents and personal photos to cloud servers. OptiSqueeze runs entirely on your device: 100% privacy, blazing-fast speed, fully offline.
🎯 COMPRESS TO AN EXACT SIZE LIMIT
Set the size you need – 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, or a custom value – and OptiSqueeze finds the best-quality version that fits under it, stepping quality down only as far as it must. If a file genuinely cannot reach your target, the app tells you honestly instead of pretending it worked. Perfect for government portals, job applications, and school submissions with strict upload caps.
🔹 COMPLETE PDF TOOLKIT (11 TOOLS)
• Compress PDF – two engines in one. The default keeps text selectable and searchable by recompressing only embedded images, deduplicating repeated fonts and pictures, and re-packing streams. Need the smallest file? Flatten mode rasterizes each page into an optimized JPEG (DCTDecode) layer.
• Smart Safety Net – compression never returns a bigger file. If the result is not smaller, your original bytes are kept.
• Merge – combine any number of PDFs, with drag-to-reorder plus one-tap sorting by name or size.
• Split – break a document into single pages, or into custom ranges like "1-3, 4-8, 9".
• Extract Pages – pull just the pages you need into a new PDF.
• Lock & Unlock – add password protection, or remove a password you know.
• Rotate – fix sideways scans with page thumbnails so you see exactly what you rotate.
• Rearrange Pages – reorder pages visually in a thumbnail grid.
• Image to PDF – turn photos and scans into one clean document.
• PDF to Image – export every page as a shareable image.
🔹 COMPLETE IMAGE TOOLKIT (11 TOOLS)
• Compress – MB to KB while staying crisp, ideal for email, chat, and web uploads.
• Resize – by longest edge, or exact width × height with optional aspect-ratio lock.
• Crop and Rotate – trim and straighten with a live preview.
• Convert – JPG, PNG, and WEBP in any direction.
• Convert HEIC – turn iPhone HEIC/HEIF photos into universally supported JPG or PNG.
• PNG ⇄ JPG and Convert to WEBP – the classic swaps, one tap.
• Remove Metadata – strip EXIF data, including GPS location, before sharing.
• Rename & Batch Rename – clean up names one by one or across a whole selection.
🔹 SMART QUALITY PRESETS
