🖼️

Drop your images here, or click to browse

JPG, JPEG, PNG and WebP — add one or many at once. You can also paste an image with Ctrl+V.

Compression Quality: 82%

Higher = better looking, bigger file. Lower = smaller file.

Target Size (KB) — exact size mode

If set, Loona auto-finds the quality/size that fits — the slider is ignored.

Output Format

Converting PNG → JPG or WebP usually saves the most.

Resize (optional)

Leave empty to keep original dimensions. Aspect ratio is always kept.

Background for JPG (transparent images)

JPG has no transparency — transparent areas are filled with this colour.

🔒 100% private: compression happens inside your browser with JavaScript. Nothing you add is uploaded to any server — close the tab and everything is gone.

How to compress an image in 3 steps

Add your images — drop them in the box above, browse, or paste. One image or a whole batch.
Choose your settings — move the quality slider, or type an exact target size like 50 KB, pick an output format and optional resizing.
Download — save images one by one, compare before/after with the compare view, or download everything together as a ZIP.

Why professionals use Loona Image Compressor

🎯

Exact target size

Forms and portals demand “photo under 50 KB” or “signature under 20 KB”. Type the number — Loona hits it automatically, no trial and error.

🗂️

True batch processing

Compress a whole folder of product photos, ID pictures or screenshots in one go and download them all as a single ZIP.

🔄

Format conversion

PNG to JPG, JPG to WebP, WebP to JPG — convert while you compress, with a background colour of your choice for transparent images.

📐

Smart resizing

Cap width and height (for example 1920 px for web, 800 px for thumbnails) while the aspect ratio is preserved automatically.

🔒

Private by design

There is no server. Your CNIC scans, family photos and documents never leave your device — unlike upload-based compressors.

👀

Before / after compare

Slide between the original and the compressed image to check quality with your own eyes before you download.

Popular uses

Online application forms (jobs, admissions, visas) that reject photos above a fixed KB size; WhatsApp and social media sharing; e-commerce product images that must load fast; blog and website images for faster pages and better Google ranking; email attachments that are too large to send; and documents or ID scans that need to stay small and private.

Frequently Asked Questions

How do I compress an image to 50 KB?

Add your image, type 50 in the Target Size (KB) box — or tap the 50 KB chip — and Loona automatically finds the quality and dimensions that fit. The same works for 20 KB, 100 KB, 200 KB or any size you type.

Are my images uploaded to a server?

No. Loona Image Compressor runs 100% in your browser using JavaScript. Your images never leave your device, which makes it safe for personal photos, ID cards and documents.

Which formats are supported?

Add JPG, JPEG, PNG and WebP images, and export as JPG, PNG or WebP — including converting between formats, for example PNG to JPG or JPG to WebP.

Will compressing reduce image quality?

At sensible settings (quality 75–90%) the difference is almost invisible while the file often shrinks 60–90%. Use the compare view to check before downloading, and keep PNG format when you need pixel-perfect lossless output.

Is it really free? Any limits?

Yes — completely free, no signup, no watermark, no daily limit. The only limit is your own device's memory.
