Why compress product images?
A product image that is 5MB does not just waste storage — it slows your store, drags your Core Web Vitals down, and quietly lowers conversion. Marketplaces add their own limits on top: Amazon caps listing images at 10MB, Etsy recommends staying lean for fast first-photo load, and email clients clip anything over a few hundred KB. Compressing before you upload keeps your listings sharp, your store fast, and your buyers patient.
This tool gives you two levers. Hit a size picks a target in KB and binary-searches the highest JPEG or WEBP quality that still fits — so you get the smallest file that still looks good, automatically. Set quality lets you drag a slider and watch the file size and preview update live, which is useful when you want full manual control over the trade-off.
Private by default
Unlike online compressors that ship your photos to a server, everything here happens on an HTML canvas inside your own browser. Your product images — often a seller's most valuable asset — never touch a server, never get stored, and never get used to train someone else's model. Close the tab and the data is gone.
WEBP is the default for web and Shopify because it is typically 25–35% smaller than JPEG at the same visible quality, and every modern marketplace and browser supports it. For Amazon listings and email newsletters, pick JPG — the safest, most universally accepted format. PNG stays lossless and is best only for images that need transparency.
Frequently asked questions
How do I reduce the file size of a product photo for Amazon?▾
Amazon accepts JPEG, TIFF, PNG, and GIF up to 10MB, but listing images load fastest and convert best under 2MB. Pick the Amazon Listing preset (or set a custom target like 500KB), choose JPG or WEBP, and the compressor binary-searches the highest quality that still fits under your ceiling — so the photo stays sharp enough for zoom while the file shrinks dramatically. Nothing is uploaded; the whole conversion runs in your browser.
What is Shopify's product image file size limit?▾
Shopify has no hard per-image byte limit but recommends images under 4472×4472px and displays them as squares; large files slow your store and hurt conversion. The Web / Shopify preset outputs a small WEBP — typically 70% smaller than a JPEG at the same visible quality — so product pages and galleries snap open on mobile. Compress once here before you upload and your store stays fast without changing how the photo looks.
JPG, PNG, or WEBP — which should I use to compress product images?▾
WEBP gives the smallest file at the same visible quality and is supported by every modern marketplace and browser, so it is the default for web and Shopify. JPG is the safest choice for Amazon listings and email newsletters because it is universally accepted. PNG is lossless and best only for images with transparency; it will not shrink past removing hidden metadata, so for flat product photos choose JPG or WEBP instead.
Is this image compressor free with no upload or watermark?▾
Yes. The compressor runs entirely in your browser on an HTML canvas — your photo never leaves your device, there is no account to create, no server upload, and no watermark is added to the output. It is free for unlimited use on Amazon, Etsy, Shopify, Instagram, Pinterest, and email product images.
