Image Compressor
Shrink JPG, PNG, and WebP file sizes right in your browser — photos never leave your device.
Drop in any JPG, PNG, or WebP and get a smaller file in seconds. Adjust the quality slider, watch the before/after size update live, and download when it looks right. Compression happens with the Canvas API inside your browser — your photos are never uploaded, which makes this one of the few image compressors that is genuinely private.
Smaller images mean faster websites, lighter emails, and uploads that fit under form limits. Most photos compress 60–90% with no visible difference, because camera files carry far more data than a screen ever displays.

Why use Nofolo’s image compressor?
No upload — truly private
Files are compressed locally with the Canvas API. Nothing is transmitted, so nothing can be stored or leaked.
Quality slider with live preview
Drag from maximum compression to near-lossless and see the output size before you commit.
Batch compression
Drop multiple images at once and download them individually or all together.
Format-aware output
Keep the original format or convert to WebP for the smallest possible files.
Resize while compressing
Optionally cap the longest edge (e.g. 1920px) — the single biggest size win for camera photos.
Free with no limits
No file count limits, no size caps beyond your device memory, no watermarks.
Frequently asked questions
Are my images uploaded to a server?
No. Compression runs entirely in your browser using the Canvas API. The images never leave your device — you can watch the network tab and see that nothing is transmitted.
How much smaller will my image get?
Typical photos shrink 60–90% at quality 70–80 with no visible difference. Screenshots and graphics with flat colors compress best as PNG or WebP; photos compress best as JPG or WebP.
Does compressing reduce image quality?
JPG and WebP use lossy compression, so very low quality settings will show artifacts. The live preview lets you find the sweet spot — most images look identical above quality 70.
What formats are supported?
JPG, PNG, and WebP as input and output. HEIC from iPhones is supported in browsers that can decode it (Safari); otherwise convert to JPG first.
Is there a file size limit?
No fixed limit. Because processing is local, the practical ceiling is your device memory — even 50 MB camera files work on a typical laptop or phone.
