Quick guide
How to compress images in bulk
- Add your images
Drag in several JPG, PNG, or WebP files, or browse your device. The first image appears in the preview.
- Choose your settings
Adjust quality for JPG and WebP, set a maximum dimension if you want to resize, and keep the original format or switch to WebP.
- Download the batch
Compress the images and get one ZIP containing the results. Each file’s new size appears in the batch list.
What changes?
JPG and WebP are re-encoded at your chosen quality. PNG is re-encoded without reducing colors. A file that cannot be made smaller at its original dimensions stays unchanged.
Image quality and privacy
Resizing preserves the image’s proportions. Re-encoding may remove camera metadata. All processing happens in your browser; your images are not uploaded to this site.
Which image format should I choose?
PNG for graphics
Keep PNG for graphics with sharp edges or transparency. The quality slider does not change PNG output; resize the image or choose WebP to try for a smaller file.
WebP for web use
Choose WebP output when your destination supports it. Compare the result size before sharing, since converting an already optimized image can sometimes make it larger.
Smaller images for websites and sharing
Reduce photo file sizes before uploading them to a website, sending them by email, or storing a batch. For web pages, choose dimensions that match how the image will be displayed, then adjust JPG or WebP quality to balance detail and size.
Keep a copy of your original images for printing or future edits. This tool is designed for still images; re-encoding does not preserve animation and may remove camera metadata.
Common questions
Is this image compressor free?
Yes. You can compress images and download the results without payment, an account, or installing software.
Will every image get smaller?
No. Already optimized files may not shrink. The tool keeps the original bytes when a same-format result is larger and you did not resize.
How do I make PNGs much smaller?
Set a maximum dimension or choose WebP output. PNG compression here is lossless, so a small PNG may already be near its best size.
Can I combine JPG, PNG, and WebP?
Yes. Add them to one batch and download the results in a single ZIP. “Keep original” preserves each file’s format.
Are my photos uploaded?
No. The browser reads and compresses your files locally. The site does not receive them.
Can I compress a large batch on my phone?
Yes, in a modern browser that supports the selected image format. Large photos and batches use device memory, so split them into smaller groups if your browser slows down or cannot finish. The interface has no fixed image-count limit, but ZIP exports must stay below 4 GB.
