Frequently Asked Questions

How do I compress multiple images at once to exact file sizes?▼
Select or drag-and-drop multiple image files into our upload area. Set your desired target size (such as 20KB, 50KB, or 100KB). The batch engine compresses each image concurrently in your browser and provides individual download buttons plus a primary Download All (.ZIP) button.
How does the Download All (.ZIP) button work?▼
Once all queued images finish processing, click Download All (.ZIP). The tool packages every compressed file into a single .zip archive directly inside your browser memory using JSZip, so you can save all files instantly without server delay.
Is there any limit on how many images I can batch compress?▼
You can compress dozens of images in a single session. To ensure smooth device performance, our engine processes 2 images concurrently in client memory, preventing mobile browser freezes or high RAM spikes.
Are any of my bulk photos uploaded to a remote server?▼
No! ExactSizeImage.com is 100% client-side and zero-backend. None of your photos, documents, or batch zip files ever leave your device or touch an external server.
