How to Batch Rename, Resize & Convert Files

Step-by-step guide to batch renaming, resizing, and converting hundreds of images, videos, and PDFs at once using Skweejee.

Quick Answer

Quick Answer: Drop a folder into Skweejee, select your target formats and size settings, and it will recursively find and convert all images, videos, and PDFs at once while preserving folder structure in the exported zip.

Key takeaways

  • Skweejee processes multiple file formats in one batch without switching tools
  • Recursive detection finds files in nested folders automatically
  • Export maintains original folder hierarchy in zip format
  • Convert images to WebP or AVIF, videos to H.265 or AV1, and compress PDFs simultaneously
  • Before/after preview with VMAF quality scores ensures no quality loss
  • All processing happens locally on your machine with no file uploads

Step 1: Drop Your Folder and Let Skweejee Find Everything

Skweejee scans nested folders automatically to queue all supported files.

  1. Launch Skweejee from the Microsoft Store
  2. Drag and drop your top-level folder into the app window
  3. Skweejee recursively detects all JPG, PNG, WebP, MP4, MOV, and PDF files inside
  4. Review the queue to confirm all files were found
  5. Original folder structure is preserved and will be maintained in the final zip export

Step 2: Choose Target Formats and Resize Settings

Configure output formats and dimensions for each file type in a single pass.

  1. Set image output format: WebP for photos, PNG for screenshots, or Auto to let Skweejee classify
  2. Define resize dimensions if needed or leave at original size
  3. Choose video codec: H.264 for compatibility, H.265 for smaller files, or AV1 for maximum compression
  4. Set VMAF quality target (90–95 for high quality, 85–89 for balanced, 80–84 for smaller files)
  5. Enable hardware acceleration (NVENC, Quick Sync, or AMF) if available to speed up video encoding
  6. PDF files are automatically recompressed without additional settings

Step 3: Batch Rename During Export

Skweejee applies consistent naming patterns across your entire batch.

  • Files are renamed during the compression process based on your preset
  • Use the smart auto-format feature to append format indicators (e.g., filename_optimized.webp)
  • Folder hierarchy is preserved inside the exported zip
  • Original files remain untouched on disk
  • Before/after view shows new filename alongside compression statistics
  • Drag-to-wipe preview confirms quality before you commit

Step 4: Automate Repeat Jobs with Watched Folders

  1. Create a Watched Folder in Skweejee with your preferred compression settings
  2. Drop new files into that folder anytime
  3. Skweejee automatically processes them to your preset without manual intervention
  4. Alternatively, right-click any file in Windows Explorer and select Compress with Skweejee
  5. Export responsive image sets at multiple widths with ready-to-paste picture tags for web developers

Frequently asked questions

Can Skweejee handle different file types in one batch?

Yes. Skweejee is the only app that processes images, videos, and PDFs together in the same run, so you never switch between tools.

How do I rename files during batch conversion?

Skweejee applies naming patterns during export and preserves folder structure in the zip, with originals left untouched.

What formats can I convert to?

Images: WebP, AVIF, JPEG, PNG. Videos: H.264, H.265, VP9, AV1. PDFs are recompressed automatically.

Does batch processing affect quality?

Skweejee uses VMAF quality targeting to find the smallest file that still hits your chosen quality score, and the before/after view confirms results.

Can I automate this for future files?

Yes. Set up a Watched Folder and Skweejee will automatically compress any files you drop in, or right-click files in Explorer to compress on demand.

Where are my files processed?

Everything happens locally on your Windows machine. No files are uploaded, and Skweejee works fully offline.

Who Should Use This Workflow

  • Photographers managing hundreds of images across nested project folders
  • Web developers creating responsive image sets at multiple widths for fast-loading sites
  • Video editors delivering client files in specific codecs and file sizes without manual Handbrake runs
