How to Use the Remove White Background
1. Step 1: Drop Your Product Photo, Logo, or Signature
Drag and drop a PNG, JPG, or WebP image into the studio, or click Load sample to test.
2. Step 2: Choose Client Mode (100% Local) or Optional HD API Mode
Keep "Client Mode (100% Browser · No Upload)" selected for private local cutout, or switch to HD API Mode ifREMOVE_BG_API_KEY is configured on your server.
3. Step 3: Adjust the Colour Tolerance Slider (8–85)
Slide tolerance (default 36) to control how aggressively off-white shadows or studio backdrops are knocked out around your subject.
4. Step 4: Select Transparent PNG or Pure White (#FFFFFF) Fill
Choose "Transparent PNG (Checkerboard)" for logos, stickers, and design layers, or "Pure White (#FFFFFF)" for Amazon, Etsy, and Shopify product photos.
5. Step 5: Click Remove Background
Run the 3.5-second edge-flood and anti-aliased alpha feathering pass and inspect the cutout on the checkerboard canvas.
6. Step 6: Download Full-Resolution PNG, ZIP, or Send to 300 DPI
Save your full-resolution cutout PNG, download a batch ZIP, or click "300 DPI ➔" to set a 300 DPI print-on-demand header.
Frequently Asked Questions
1. How do I make a white background transparent on a JPG logo?
Drop the JPG logo above; the tool converts the white background to alpha transparency and exports a transparent PNG.
2. Does this work for scanned ink signatures?
Yes! Increase the tolerance slider slightly (around 45–60) to remove grey paper shading around your pen strokes.
3. How do I remove a background from an image for free with no upload?
Drop your image in Client Mode (the default), adjust the Colour Tolerance slider if needed, and click Download Result to save a transparent PNG processed 100% in your browser.
4. What is the difference between Client Mode and HD API Mode?
Client Mode runs entirely on your device using corner background sampling and colour-distance alpha matting with zero server uploads. HD API Mode sends the image to our backend proxy (/api/remove-bg) when REMOVE_BG_API_KEY is configured in .env.
5. How do I remove a white background from a JPG logo or scanned signature?
Drop your JPG logo or signature in Client Mode and keep Replacement Background set to "Transparent PNG". For scanned paper signatures, increase tolerance to 45–60 to clear grey paper shading.
6. How do I create a pure white (#FFFFFF) background for Amazon, Walmart, or Etsy?
Select "Pure White (#FFFFFF — Amazon/Etsy)" in the Replacement Background dropdown. The tool knocks out the original backdrop and composites your product onto pure RGB(255,255,255) white.
7. Does Vexolora downscale my cutout image to low "preview" resolution?
Never. Unlike cloud sites that cap free downloads at 500×500 px and charge credits for HD, our Client Mode exports 100% of your original pixel dimensions for free.
8. How does the anti-aliased alpha feathering prevent jagged cutout edges?
Instead of a harsh binary 0/1 cutoff, pixels near the tolerance threshold receive a smooth proportional alpha ramp, keeping curved edges natural.
9. Can I batch remove backgrounds from multiple product photos at once?
Yes! Drop multiple studio product photos or logos, dial in your tolerance, and click "Download ZIP".
