Smaller files, same photos, no per-image busywork
Large, unoptimized photos are one of the most common causes of a slow website or an email attachment that bounces. Most online compressors handle this one image at a time, which turns "compress the product photos" into an afternoon of uploading, waiting, and downloading. Ecom Studio applies one compression setting to an entire batch, so a folder of fifty photos takes the same number of clicks as one.
You get a live quality slider rather than a fixed preset, plus the option to convert format at the same time — for example, re-exporting a batch of PNG screenshots as compressed WebP, or bringing oversized camera JPEGs down to a web-friendly size.
How to compress images in bulk
- Drop your photos into Ecom Studio — one file or several hundred.
- Open the Export tab and choose JPEG, PNG, or WebP as the output format.
- Drag the quality slider until the preview looks right — lower quality means a smaller file.
- Select your photos and click "Export Batch" to download every compressed photo as one ZIP.
Frequently asked questions
How much smaller will my images get?
It depends on the source image and the quality level you choose. Switching to WebP at 80-90% quality typically cuts file size noticeably compared to an unoptimized JPEG or PNG, with little visible difference.
Can I compress a whole folder of photos at once?
Yes. Upload as many photos as you have, set one quality level, and Ecom Studio applies it to the entire batch before packaging everything into a ZIP.
Will compressing reduce image quality?
Some quality loss is inherent to JPEG/WebP compression, which is why Ecom Studio gives you a live quality slider — drag it down until file size drops but the photo still looks right, rather than a fixed one-size-fits-all setting.
Which format compresses best — JPEG, PNG, or WebP?
WebP generally produces the smallest files at a given quality level for photos. PNG is lossless and best for graphics/screenshots with flat colors, but produces much larger files for photos. JPEG sits in between and has the widest compatibility.
Are my photos uploaded anywhere to be compressed?
No — compression happens locally in your browser. Nothing is sent to a server, so there's no wait for an upload and no privacy concern about where your images end up.
