BULK WORKFLOW
One set of image settings for an entire product batch.
Seller Image Studio processes images locally in your browser, so a product-photo folder does not need to be uploaded before compression begins.
Choose WebP, AVIF or JPEG, set a quality level and maximum longest edge, then export the completed files together.
Tune the batch once
Use the same output format, quality mode and resize limit across every product image for consistent storefront assets.
Review real savings
See the original and finished size for each image, plus the total reduction for the batch before downloading.
Export together
Download individual files or package completed images in a ZIP. Compatible browsers can also save beside the originals.
Prepare a complete listing batch without sending client or product photography to an image-processing server.

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.

Common questions.
How many images can I compress at once?
Seller Image Studio accepts up to 100 supported images in one batch to protect browser memory and keep the queue responsive.
Can I compress a complete image folder?
Yes. Add a folder to import supported JPG, PNG and WebP files. Chrome and Edge can save results beside the originals after you approve access; other browsers can download a ZIP.
Are my images uploaded?
No. Compression, resizing and format conversion run on your device. The product images are not uploaded to Seller Image Studio.
Which output formats are available?
You can export WebP, AVIF or JPEG and choose a smallest, balanced or high-quality mode.
