How many images can I compress at once?

Up to 20 files, 40 MB each. Add another batch after you download and clear.

Do all files share the same settings?

Yes. Quality, longest edge, and output format apply to every item. Changing a control re-runs the current list.

Can I mix JPEG, PNG, WebP, and HEIC?

Yes. Match original keeps JPEG, PNG, WebP, and AVIF as their own types. HEIC in a mixed batch becomes JPEG. You can also convert the whole batch to JPEG, WebP, PNG, or AVIF.

Are my photos uploaded in a batch?

No. Each file is read and compressed in this browser, same as a single image.

Compress multiple photos at once

PixShrink can shrink a stack of photos in one pass. Add up to 20 files — including iPhone HEIC — set quality and a longest-edge cap, and each image is processed on your device.

Use it after a shoot, before a slide deck, or when a folder of screenshots needs to fit an email. Settings apply to the whole batch; you can still download files one by one.

How to compress a batch

Step 1
Choose several files
Drop them together or pick multiple in the file dialog. Skip anything over 40 MB. Room left in the list is 20 minus what you already added.
Step 2
Set quality and longest edge once
75% and 1920px is a solid default for web and chat. Use 1280px or 800px for thumbnails. Original keeps full resolution and only re-encodes.
Step 3
Wait for each row to finish
Every file shows before/after size. If one says “No reduction,” that original was already small for these settings — it is still safe to download.
Step 4
Download all, or save a single file
Download all grabs every finished result. Clear removes the batch from memory. Closing the tab does the same.

Settings that scale across a folder

Match original is usually right for mixed JPEG and PNG. Switch the whole batch to WebP only when every destination accepts it.

A longest-edge cap is the fastest way to cut camera-roll size. Quality then fine-tunes the last 10–30%.

When a batch feels slow

Large PNGs and phone browsers take longer. Compress in smaller groups, drop the longest edge, or use a desktop tab.

Files never leave this device, so a pause is local work — not an upload queue.
