Media & File Processing

Merge multiple PDF documents or extract specific page ranges directly within your browser. All operations run locally using your device resources, with no server uploads required for supported unencrypted PDFs.

Using ONNX Runtime Web, automatically crop the background of people and products in images on the browser.

Compress JPEG, PNG, WebP, and HEIC/HEIF images and export them as JPEG, PNG, or WebP in your browser. Adjust target file size and maximum dimensions with client-side batch processing.

Resize browser-supported images by percentage or custom dimensions and export JPEG, PNG, or WebP.

No software installation required, record browser tabs and entire desktop screen and save locally.

Erase unwanted objects with a brush mask using Canvas patch-matching and neighborhood color averaging without AI models. Best for small areas and simple backgrounds, with PNG export.

Minimize file size by removing unnecessary metadata, empty elements, and editor-specific tags such as Illustrator and Inkscape from your SVG code.

Decode audio files (MP3, WAV, M4A, OGG) on your browser, convert them all at once to WAV or WebM format, and save them.

Completely removes personal information and metadata contained in images (JPEG, PNG) such as GPS location information, photography equipment, and date and time of photography.

Create an original animated GIF by uploading multiple image files and setting the frame order and playback speed (FPS).

Supports side-by-side grid playback for multiple formats, as well as sequential chain merging for GIFs. Files are processed locally in your browser.

You can decode the audio file, display the waveform, and intuitively specify the cutting range using the slider and save the cut.

Cut out an arbitrary range from a video such as MP4 and save it as a flip animation GIF or lightweight video file using Canvas drawing.

Standard browser voice preview may use external processing; this tool cannot export the standard voice. A separate synthetic robot voice can be saved as WAV on successful decode, or otherwise in the actual recorded WebM/MP4-family format.

Generates a high-quality QR code from any text or URL, and supports changing the color scheme and embedding a custom logo image in the center.

Read and analyze QR codes at high speed by loading image files or real-time scanning with a PC or smartphone camera.

Upload an image and get the color code (HEX/RGB/HSL) with a single click while viewing the pixel-by-pixel magnifying glass preview.

Freely create drawings and handwritten notes on your browser, and save and download them as PNG or JPEG images.

Blur or mosaic (pixelize) any part of the uploaded image by hand-drawing with a brush or using the rectangular selection tool.

Generates major one-dimensional barcodes such as JAN code (EAN-13/8), CODE39, ITF, Codabar, etc. on Canvas from input numbers with high precision.

Convert HEIC and HEIF photos to JPEG or PNG in your browser (up to 30 files, max 30MiB each) with adjustable quality. Decoding depends on device resources with no unlimited conversion guarantee.

Completely converts Excel file (.xlsx/.xls) sheet data and CSV files into each other on a local browser, taking into account the state of formulas and character encoding.

Render a vector image (SVG) at high resolution and convert it to a transparent PNG, or trace a PNG image (run-length path) and convert it to an editable SVG.

You can adjust and save the playback speed (tempo) and pitch/key of audio data (MP3, WAV, M4A, etc.) independently on the browser.

Extract text from images directly in your browser using client-side OCR. Character recognition processes locally once required language data and engine assets are downloaded.

Encrypt (protect) and restrict viewing of PDF files with a password, or remove (decrypt) the password and convert to a plain PDF without a password.

You can view, edit, and delete Exif metadata such as the shooting date and time, camera device information, and GPS location information included in images (JPEG) directly on your browser.

Edit and preview SVG path data (d attribute) intuitively using drag-and-droppable anchor points and control handles.

Merges multiple icons and small images into one combined image (sprite image), and automatically outputs the display position specification code (background-position) using CSS.

Generate dynamic frequency spectrum and waveform animation videos from audio files. You can record locally and download it as a WebM video.

We beautifully synthesize screenshot images from smartphones and PCs into the frames of the latest iPhones, MacBooks, and monitors to generate images for PR materials and materials.

Compress multiple files into one ZIP file, or expand (unzip) an existing ZIP file on your browser.

Load a large number of file names by copying and pasting or dragging and dropping, and simulate rules such as string replacement, regular expressions, and sequential numbering in real time.

Extract an arbitrary time range from a video (MP4/WebM), sample frames, and convert them to high-quality animated GIF, or vice versa.

Easily crop images to your preferred ratio (1:1, 16:9, 4:3, free) by dragging. It also supports circular cutouts for avatars.

Swaps the left and right channels of the audio file, mixes it to monaural, extracts L/R individual channels, and adjusts the localization panning.
