Bulk-resize and compress product images — without uploading them anywhere.
Turn a folder of 200 product photos into marketplace-ready WebP files in a single pass. Everything runs inside your browser, so your images never touch a server.
No credit card required · 20 free images every month · 100% local processing
Nothing leaves your device
No upload queue, no server-side processing, no retention policy to worry about. Your product photos are decoded and re-encoded locally by your own CPU.
Batch up to 200 at once
Drag in a whole shoot, apply one set of rules, and download a single ZIP. Each file keeps its own name so it drops straight back into your product catalog.
Marketplace-aware sizing
Cap width and height in one pass, convert to WebP or JPEG, and hit the image limits Shopify, Amazon and Etsy actually enforce.
How it works
Three steps, no account needed to try it.
Drop your images
Select up to 200 PNG, JPG, WebP or AVIF files from your computer.
Set one rule
Pick an output format, a quality level and a maximum dimension. Applied to every file.
Download the batch
Grab individual files or the whole set as a ZIP, with a before/after size readout.
Why upload-free matters
Most online image compressors work by sending your files to their servers. For a product catalog that means your unreleased photos sit on someone else's disk, under someone else's retention policy. PixBatch does the work locally: the browser decodes the file, redraws it at the size you asked for, and re-encodes it — then you save the result. Nothing is transmitted, so there is nothing to retain.
No upload, no retention
We never receive your image bytes. There is no storage bucket and no delete button to trust.
No bandwidth cap
Processing speed depends on your machine, not on our upload limits or queue depth.
Works offline after load
Once the page is open, the processing pipeline needs no network round trip per file.
Built for the limits marketplaces enforce
Shopify & WooCommerce
Cap the long edge at 2048px and export WebP to cut page weight without visible loss.
Amazon
Resize to the 2000px recommendation for zoom-enabled listings, then export JPEG or PNG.
Etsy & marketplaces
Standardise a mixed shoot into one dimension so your grid stops looking uneven.
Questions
Are my images really not uploaded?
Correct. The file is read by your browser through the File API, drawn onto a local canvas and re-encoded there. The only thing our API receives is a counter of how many images you processed, so the free plan can be metered.
What happens when I hit the free limit?
The free plan covers 20 images per calendar month. Past that, processing pauses until the next month or until you upgrade — your files are never held hostage.
Which formats can I export?
WebP, JPEG and PNG. WebP is usually the smallest for photographic product shots; PNG keeps transparency for cut-outs and logos.
Does it work on large shoots?
Yes — up to 200 files per batch, processed three at a time so the browser stays responsive. Pro removes the monthly image cap.
