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.
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.
Free to use · No image uploads · No forced sign-upFAQ
Common questions.
Which image formats can I import?
You can add JPG, JPEG, PNG and WebP images. SVG files are not accepted for safety and because they need a different workflow.
Is Seller Image Studio really free?
Yes. The current image optimizer does not require an account, payment card, subscription, conversion credits or an advertisement before download.
Does compression reduce image quality?
Some formats use visual compression. Balanced mode is tuned to reduce file size while preserving the details customers notice.
Why is AVIF slower?
AVIF uses a more intensive encoder to create smaller files. The work runs off the main interface so you can still stop the batch.
Can results save back to my original folder?
Yes in Chrome and Edge: choose Add folder, approve read and write access, then converted files are saved beside each original without replacing it. Other browsers can still import folders and download the results as a ZIP.
Does Seller Image Studio use cookies?
The image optimizer does not use analytics, advertising or profiling cookies, and it does not store your images in browser storage. If you open the site through a protected sign-in page, the hosting service may use strictly necessary session cookies to keep that access secure. They are not used by Seller Image Studio for analytics or advertising.
Do platform presets guarantee marketplace approval?
No. They provide practical format, quality and dimension starting points. Marketplace rules can vary by country, category and image type, so always review the latest requirements before publishing a listing.
