36-Image Converter: Batch Resize, Rotate & Format Change Tool

36-Image Converter: Convert JPEGs, PNGs & GIFs in One Go

What it does

• Batch-converts up to 36 images at once between common formats (JPEG, PNG, GIF).
• Preserves filenames or appends configurable suffixes.
• Offers options for quality, color profile handling, and transparency support.

Key features

• Bulk format conversion: JPEG ↔ PNG ↔ GIF with single-click processing.
• Compression/quality control: Set JPEG quality (e.g., 60–100%) and PNG compression level.
• Transparency handling: Preserve PNG/GIF transparency; optional background fill when saving as JPEG.
• Resize and crop: Resize by pixels or percent; common aspect-ratio presets; center/auto crop.
• Rotate and flip: Auto-rotate using EXIF orientation or manual rotate/flip.
• Filename management: Keep original names, add prefix/suffix, or use numbered sequence.
• Preview & batch settings: Preview one image with applied settings; apply to all 36.
• Speed & resource use: Multithreaded processing for faster throughput; progress indicator and estimated time.

Typical workflow

1. Add up to 36 images (drag-and-drop or file picker).
2. Choose output format and quality/compression settings.
3. Configure resize/crop and transparency/background options if needed.
4. Set output folder and filename rules.
5. Click Convert and monitor progress; download or open output folder when done.

Best-use scenarios

• E-commerce: Convert product PNGs to optimized JPEGs for faster page load.
• Social media: Resize and convert mixed-format batches to required specs.
• Web publishing: Create uniform-format image sets with consistent sizing and compression.

Limitations to watch for

• Animated GIFs may be flattened unless explicitly supported.
• Converting formats with transparency to JPEG requires a background color choice.
• Quality loss with repeated lossy conversions (e.g., JPEG → JPEG).

If you want, I can write a short how-to guide for a specific conversion (e.g., PNG→JPEG with transparency handling) or create example command-line steps for ImageMagick or a sample script.
