What You Can Do with OFFiler
Merge, split, compress, and extract pages from PDF
Combine multiple PDFs, extract specific pages, reduce file sizes, or remove password protection — all without Adobe Acrobat or any desktop software. Perfect for organizing business documents, tax filings, and everyday office paperwork.
Capture with your camera and turn it into a PDF instantly
Use the Camera Capture tool to photograph documents, receipts, or whiteboards, then chain directly to PDF conversion. No scanner app installation required — and your photos are never saved to the cloud. Great for digitizing receipts, contracts, and meeting notes.
Convert, resize, compress, and reformat images
Convert between JPEG, PNG, WebP, and GIF formats, resize to exact dimensions, and compress for SNS or email — all in your browser. Safe for confidential images since nothing leaves your device. Ideal for web optimization and attachment size reduction.
Create Japanese seal stamps (hanko) in your browser
Design round stamps, square stamps, date stamps, and personal seals (認印) for free in your browser. Customize font, color, and size, then download as PNG for use in digital documents and PDFs. No stamp-maker software or online store needed.
Extract audio (MP3) or frame images from video
Extract audio from MP4, MOV, and WebM videos as MP3 or WAV, or save any frame as a PNG image — no video editor required. Useful for pre-processing meeting recordings, creating YouTube thumbnails, or capturing slides from lecture videos.
Check images for personal information before posting to SNS
Check images for embedded EXIF data (GPS location, camera model, timestamp) and QR codes or barcodes before sharing on SNS or in business contexts. Prevents accidental personal-data exposure. All processing happens in your browser — images are never uploaded.
Convert, format, encode, and decode text
Full-width/half-width conversion, uppercase/lowercase, JSON formatting and validation, Base64 encode/decode, URL encode/decode, hash calculation (MD5, SHA-256, SHA-512), regex replace, and line sort/deduplication — a complete set of everyday text processing tools for developers and writers.
Chain tools together to complete multi-step tasks in one flow
Pass the output of one tool directly to the next — no downloading and re-uploading needed. Whether it's PDF compress → markup, or camera capture → PDF → compress, chaining tools turns a multi-step workflow into a seamless sequence.
Your files never leave this device
Everything runs entirely inside your browser. The contents, filenames, and metadata of your files are never sent to any external server.
Open your browser's developer tools (Network tab) and verify for yourself that no file is ever uploaded.
