Step 1: Pick a direction
Two tabs: images to Base64, or Base64 to images. Pick whichever you need. Both support batch processing.
Try the example image if you just want to poke around before uploading anything of your own.
Step 2: Add your data
Depends on which direction:
Images to Base64: drag and drop files, browse for them, or paste an image URL
Base64 to images: paste your Base64 strings into the text box, one per line
Format detection: the tool figures out what the image format is on its own
Step 3: Convert
Hit the button and let it run:
Web Workers handle the heavy lifting in the background
Progress shows as it works through the batch
Validation runs automatically so you don't get bad output
Step 4: Grab your results
Once it's done:
Preview decoded images with navigation for multiple files
Copy individual Base64 strings or all of them at once
Download Base64 as TXT files, or images as a ZIP
Remove individual items or reset the whole workspace
Tip: If you're embedding a bunch of icons, use 'Copy All Base64' instead of clicking each one. Saves you from doing it piece by piece.
Your Data Stays on Your Device
Unlike other online Base64 tools, PixDuplicate does all the work locally in your browser. That means:
