FAQ
Wildberries photo questions
Answers to common questions from marketplace sellers.
What image size does Wildberries require?
Wildberries recommends 900×1200 pixels with a 3:4 aspect ratio. This is the optimal size for product cards on the website and mobile app.
Does this crop or stretch my images?
The tool crops to center-fit 3:4 ratio while preserving quality. No stretching occurs — images always look sharp and professional.
Can I process multiple product photos at once?
Yes! Drag and drop multiple images or upload a ZIP archive with folders. Folder structure is preserved when you download, making bulk processing easy for sellers with many products.
What JPG quality should I use?
We recommend 85-90 for the best balance of quality and file size. Higher values (90+) give sharper images but larger files. Lower values (70-80) reduce size but may show compression artifacts.
Is my data private and secure?
All processing happens locally in your browser. Your product photos are never uploaded to any server. This is 100% private — we never see your images.
What file formats are supported?
We support JPG, PNG, WebP, AVIF, and HEIC input images. All output files are optimized JPG at 900×1200 pixels, ready for Wildberries upload.
Do I need to install any software?
No installation needed. This tool runs entirely in your browser. Just open the page, drop your images, and download the results.
Can I use this for other marketplaces?
While optimized for Wildberries 3:4 format, the 900×1200 size works well for many e-commerce platforms that prefer portrait product images.
