Turn 30 minutes of file chores into three calm minutes.
Batch rename, extract image text, create documents from text, enhance images, merge PDFs, convert data and detect duplicates. Most file work stays in your browser; High Accuracy OCR clearly discloses transient cloud processing before it runs.

Online Batch File Renamer
Drop in a folder's worth of files, combine prefix, suffix, text replacement and numbering rules, then review every old-to-new name before download.
Use this toolRename Files in Sequential Order
Start at any number, count by any increment, place numbers before or after the name, and drag files into the exact order you need.
Use this toolReverse Number File Renamer
When the newest file must come first or a page set needs reverse numbering, generate a descending sequence and inspect it before download.
Use this toolCustom Order File Renamer
Arrange files in the order that makes sense, then number that exact sequence. On mobile, use the up and down controls instead of dragging.
Use this toolImage Batch Converter
Convert up to three images into one consistent format. Processing stays in your browser, and only successful files count toward the daily quota.
Use this toolBatch Image Resize, Crop & Zoom
Output by percentage or exact dimensions, choose a common aspect ratio and move the focal point, with format, quality and credit cost shown first.
Use this toolBatch Image Clarity & Color Enhancer
Apply light edge sharpening and correct brightness, contrast and saturation across a batch, entirely on your device.
Use this toolBatch Image Compression & Size Optimization
Choose output quality and format, then see actual dimensions, bytes and savings for each result—never a made-up estimate.

Merge PDFs in your chosen order, split or extract page ranges, or create one PDF from ordered JPG and PNG images.
Use this toolBatch CSV, TSV & JSON Conversion
Detect each input by extension, batch-export one target format, preview the first output and download files individually or as a ZIP.
Use this toolText to Document Converter
Turn text into common document files with clean spacing or preserved line breaks. Keep the default white page, choose a calm built-in background, or upload your own image and preview it first.
Use this toolImage to Text OCR & Document Export
Choose transient High Accuracy OCR or no-upload Local Privacy OCR, review the recognized text, then export common document formats.
Use this toolContent-Level Duplicate File Finder
No filename guessing: narrow candidates by byte size, then calculate content fingerprints and report only byte-identical files.
Use this toolDefaults that prevent common mistakes.
