About Filewisp

Filewisp handles file jobs that should not require installing another app, including image and PDF work plus CSV, JSON, Parquet, and AWS export conversion.

Each tool states what it accepts, what it produces, and what may be lost during conversion. Keep the original file when quality, transparency, or metadata matters.

Filewisp is operated by Kosuda, a web engineer born in 1998 with five years of professional experience, mainly in web application development.

I built the site after repeatedly needing to make one small change to an image or PDF during ordinary web work. The interface follows those short, practical jobs.

Existing tools are checked for conversion errors, unclear instructions, and missing format details. Those fixes take priority over adding pages for their own sake.

New tools and major fixes are recorded in the update history below.

Tools marked 'No upload' process files in the browser and do not send them to an external server.

Bug reports are most useful when they include the device, browser, source format, and exact error message.

The site may display ads to cover operating costs such as the domain and hosting. All tools remain free with no feature restrictions, regardless of advertising.

Ad placements are kept away from tool controls so they never interfere with your work. Cookie usage is described in detail in the privacy policy.

June 2026: Rebranded to Filewisp with a full redesign. Converters gained multi-file batch processing, progress indicators, and ZIP download; a TIFF conversion bug was fixed; and new problem-solving guides (HEIC, WebP, email attachments, PDF size limits) were published.

March-May 2026: Launched 50 image, PDF, and data tools. In July 2026, added CSV repair, Parquet inspection, background transparency, and service-specific AWS converters, bringing the current directory to 67 tools.
