Deftfile

Free tools for everyday file chores: make a file fit an upload limit, resize a photo for an ID, or fix subtitle timing. Everything runs in your browser.

• Compress Image to Exact KB

  Shrink a JPG or PNG photo under a size limit such as 20KB, 50KB or 100KB for application forms.

• Compress PDF to Exact KB

  Make a PDF fit an upload limit such as 100KB, 200KB or 500KB. Pages are turned into images, so text is no longer selectable.

• Passport & Visa Photo Resizer

  Crop a photo to UK, Schengen and EU 35×45 mm and other passport or visa sizes, then download a 300 dpi JPG or a 4×6 in print sheet.

• Shift Subtitle Timing (SRT & VTT)

  Move every line of a subtitle file earlier or later to fix out-of-sync subtitles, and convert between SRT and VTT.
