PNG Converter for Windows — Convert PNG in Batch to Any Format

PNG files pile up fast: UI assets, screenshots, game sprites, scanned documents, web graphics. At some point you need dozens or hundreds of them in a different format — or you need to convert JPEG, TIFF, BMP, or WebP files to PNG to preserve transparency. Processing them one by one in an image editor takes hours. Total Image Converter handles the entire batch in a single run, in either direction: PNG to any format, or any format to PNG.

What Is the PNG Format

PNG (Portable Network Graphics) was created in 1996 as a patent-free replacement for GIF. It uses lossless compression: every pixel in the output matches the input exactly, with no quality loss on repeated saves. That makes PNG the correct choice when pixel accuracy matters.

Key technical facts about PNG:

• Color depth: supports 24-bit (RGB) and 32-bit (RGBA) images, plus 8-bit grayscale and indexed color.
• Alpha channel: full 8-bit per-pixel transparency, not just a single transparent color like GIF.
• Lossless compression: file size is larger than JPEG for photographs, but quality is never degraded.
• No EXIF camera data: PNG carries only basic metadata; camera EXIF is stored in a separate tEXt chunk and is often stripped by editors.
• No animation: PNG is static. Animated sequences use APNG or are a separate format entirely.

PNG is the default format for UI screenshots, software mockups, icon sets, web graphics with transparent backgrounds, and any image that will be edited multiple times before final delivery.

PNG vs. Other Formats

PNG wins when you need transparency and pixel-perfect quality. JPEG wins when file size matters and the image is photographic. TIFF is preferred in print pipelines. Converting from PNG to one of these formats — or back to PNG from any of them — is a routine task in any image workflow.

How to Convert PNG Files in Batch

1. Download and install Total Image Converter. The 30-day trial is fully functional — no email or credit card required.
2. Open the program. The left panel shows a folder tree. Navigate to the folder that contains your PNG files. Thumbnails appear in the file list on the right.
3. Select the files you want to convert: click one, Shift-click for a range, or press Ctrl+A to select everything in the folder. For converting other formats to PNG, navigate to the folder with those source files instead.
4. Click the target format button in the toolbar: JPEG, TIFF, BMP, PDF, WebP, or PNG (if converting from another format to PNG).
5. In the conversion wizard, configure output options: JPEG quality level, TIFF compression type, resize dimensions, or color depth. For PNG output, set compression level (1–9) to balance file size and encoding speed.
6. Choose the destination folder and click Start. All selected files are converted and saved. Original files remain untouched.

Command-Line PNG Conversion

Total Image Converter includes a command-line version for scripts, scheduled tasks, and server pipelines. To convert all PNG files in a folder to JPEG with 85% quality:

TotalImageConverter.exe C:\Images\*.png C:\Output -c jpeg -jpegquality 85

To convert all JPEG files in a folder to PNG (lossless, alpha preserved from source if applicable):

TotalImageConverter.exe C:\Photos\*.jpg C:\Output -c png

Wrap either command in a .bat file and drop it into Windows Task Scheduler to run nightly conversions automatically. This is useful for web pipelines that need to regenerate PNG assets from master TIFF files on a schedule.

Why Use Total Image Converter

Alpha channel preserved on every conversion

When you convert PNG to TIFF or PNG to WebP, the 8-bit alpha channel is carried through to the output. Convert PNG to JPEG and the tool correctly flattens the transparency against a white (or custom) background rather than producing corrupt edges. You control how transparency is handled, not the converter.

Batch speed on large folders

Select 2,000 PNG screenshots and click Start. Total Image Converter processes them sequentially using native Windows libraries — no upload queue, no per-file dialogs, no manual steps between files. A folder of 500 full-HD PNGs typically converts to JPEG in under two minutes.

Convert to PNG and from PNG

The same tool works in both directions. Send JPEG, TIFF, BMP, WebP, TGA, PSD, RAW, and 30+ other formats to PNG. Or export your PNG assets to JPEG, PDF, TIFF, or any other format your workflow requires. No need to own a separate converter for each direction.

Resize and crop in the same pass

Need PNG thumbnails at exactly 256×256 pixels? Set the target dimensions in the conversion wizard. The resize and format conversion happen in a single pass. You do not need to pre-process images in a second tool before converting.

Works entirely offline

Total Image Converter runs locally on your Windows PC. No files leave your machine. This matters when converting proprietary UI assets, client deliverables, or confidential screenshots that should not be uploaded to a third-party website.

Total Image Converter Customer Reviews 2026

"I work with large sets of PNG assets and regularly need to deliver them as JPEG or WebP for different clients. Total Image Converter handles entire export folders in one run, and critically, it handles alpha channels correctly — no ugly white fringes or silent transparency stripping. The batch speed alone is worth the price."

Claire Ashworth UI/UX Designer

"I use this to convert our PNG design exports to optimized JPEG and WebP for the build pipeline. The command-line interface is clean and scriptable — I just dropped it into a .bat file that runs before deployment. Processed over 3,000 images from a recent project without a single error."

Marcus Lindqvist Front-End Developer

"Converting sprite sheets and textures from TGA and BMP to PNG is a regular part of my workflow. Total Image Converter does this accurately with no color shift. Batch mode is solid. My only suggestion would be a progress log saved to a file for large runs, but the conversion itself is reliable."

Tomasz Wierzbicki Indie Game Developer
