Target-size control
Useful when a portal says 100 KB, 200 KB, 500 KB or 1 MB. The compressor works toward the target instead of making you trial-and-error quality sliders.
SMART IMAGE COMPRESSION
Compress Images Online — Fast, in Bulk, to the Size You Need
Shrink JPG, PNG and WebP images without turning the job into a repetitive upload-download cycle. Compress a batch, choose a target size when a form has a strict limit, or optimize for web and email.
Smart batch compressor
Compress a whole image set in one pass
Add images or a ZIP, choose a target, review savings, and download the finished set as one organized ZIP.

Quick targets
Images are processed in your browser for this workflow; they are not uploaded just to compress them.
Built around the job you actually need to finish
A good compressor should not make you guess. Pick the constraint, process the whole set, and get files that are ready for the next step.
Batch first
Add a group once, apply consistent rules, and download the finished set together. This is especially handy for applications, scans and product photography.
Private by design
Browser-side processing keeps ordinary compression jobs on your device rather than requiring an upload just to reduce file size.
Common reasons people compress images
The right setting depends on where the image is going next.
Government & job portals
Get photos and signatures under a practical KB limit without repeatedly changing quality by hand.
Websites & ecommerce
Optimize a whole product-photo folder consistently, keep useful dimensions, and leave with one ZIP.
Email & messaging
Shrink large photo sets before sharing so attachments are easier to send and store.
Scans & documents
Reduce scanned images for forms and applications while keeping text readable.
How to compress an image without making it unusable
Start with the destination rather than chasing the smallest possible number. For a website, reducing dimensions and using an efficient format can make a bigger practical difference than aggressively lowering quality. For an application form, the hard requirement is usually a maximum file size, so target-size mode is the more useful starting point.
If you have several images, add them together. Applying one consistent rule to the complete set avoids the common problem of ending up with ten slightly different quality settings and ten separate downloads. When the batch is finished, download the ZIP and move on to the next step.
JPG, PNG or WebP: which should you choose?
JPG is usually the practical choice for photographs because it can reach small sizes efficiently. PNG is better when lossless detail or transparency matters. WebP is often a strong modern web format when your destination supports it. There is no single “best” format; the useful choice is the one that matches the destination and quality requirement.
Why target-size compression is different
“Compress to 100 KB” is a different job from “make this image smaller.” A useful target-size workflow has to balance dimensions, quality and format so the result stays usable while approaching the requested limit. That is why MaxScanner treats target size as a first-class workflow rather than hiding it behind a generic quality slider.
Frequently asked questions
Can I compress multiple images at once?
Yes. Add up to 100 JPG, PNG or WebP images, choose your settings once, and MaxScanner processes the batch and packages the results into a ZIP file.
Can I compress an image to a specific KB size?
Yes. Choose a target such as 50 KB, 100 KB, 200 KB, 500 KB or 1 MB. Target-size mode automatically balances JPEG quality and dimensions to get as close as practical to the requested size.
Can I keep the original dimensions?
Yes. Leave the maximum-dimension control above the source dimensions. The compressor will not enlarge a smaller image, and target-size mode only reduces dimensions when that is needed to meet the size goal.
Which image formats are supported?
The smart batch compressor accepts JPG, PNG and WebP and can output JPG, PNG or WebP. Target-size mode uses JPG because it gives more predictable file-size control.
Are my images uploaded to a server?
No. The image compression workflow is designed for browser-side processing, so the image bytes do not need to be uploaded to MaxScanner just to reduce their size.
What is the best format for photos?
JPG is a practical choice for photographs when small files matter. WebP can be a strong choice for modern websites, while PNG is better when lossless quality or transparency matters.
How do I compress images for a government or job application form?
Use the target-size presets, starting slightly below the portal limit. Check the resulting file size and dimensions before uploading. This is usually more reliable than repeatedly guessing image quality.
Can I download all compressed images together?
Yes. Batch results can be downloaded as an organized ZIP, which is useful when you are preparing many photos, scans or product images at once.
