TIKTOK SHOP WORKFLOW
Create a consistent set of listing images without uploading source files.
The TikTok Shop preset uses high-quality JPEG and starts with a 1600 px maximum longest edge. It creates new files and preserves the original aspect ratio.
Requirements may differ by region, category and listing surface, so verify current Seller Center guidance before publishing.
Preserve proportions
Resize the longest edge without stretching the image or enlarging smaller product photos.
Process up to 100 files
Prepare a launch or catalog batch with the same settings and download the results together.
Check regional rules
Use the preset as a starting point and verify the current image requirements for your TikTok Shop market and category.
Keep the batch consistent, preserve the originals and review marketplace requirements before the final upload.

WHY IT EXISTS
A free image optimizer for people who just need the job done.
Seller Image Studio is a browser-based batch image converter for online shops. It resizes and converts product photos to WebP, AVIF or JPEG, with practical starting presets for websites, WooCommerce, Shopify, Amazon and TikTok Shop.
No account, credit card, daily conversion credits or ad-watching step is required. Add your images, choose the result you need and download the finished files.
Your images stay local
Processing happens on your device. Product photos are not sent to our servers, added to an account or used for training.
Built for real batches
Convert individual files or a complete folder, then download the results together instead of repeating the same task image by image.
Originals stay untouched
The converter creates new files and never replaces your source images. You remain in control of every original.
Useful, honest presets
Storefront presets give you a sensible format, quality and size to start from. You can still adjust every setting before processing.
Image tools should help you finish a listing—not interrupt the work with pop-ups, trial limits or a subscription screen.

Does the tool crop listing images?

Does the preset guarantee listing approval?
No. Marketplace requirements can change and vary by region, category and image type. Confirm the current rules before publishing.
Can I process a complete product-photo folder?
Yes. Import supported images from a folder, apply one preset and download the completed batch as a ZIP.
