WhatsApp compresses images above 5 MB automatically, often with visible quality loss. Use our WhatsApp preset to stay under 1 MB for sharp, fast-loading photos.
🔒 100% Private
All compression happens inside your browser using the Canvas API. Your images never leave your device. No server, no storage, no tracking.
⚡ How It Works
We draw your image onto an HTML canvas and re-export it at your chosen quality level. JPEG compression typically reduces file size by 60–85% with no visible difference on a phone screen.
📦 Batch Compress
Select multiple images at once. All files are compressed to your chosen quality setting and individually downloadable — no ZIP required.

Frequently Asked Questions
How much can I compress an image?
At WhatsApp quality (60%), most photos shrink by 70–85%. A 4 MB DSLR photo typically compresses to under 600 KB with no visible quality loss on a phone screen.
Does my image get uploaded to a server?
No. Everything happens in your browser using JavaScript and the Canvas API. Your photos never leave your device. This makes the tool both fast and completely private.
What formats are supported?
JPG/JPEG, PNG, and WebP. Compressed output is always JPEG for maximum size reduction. PNG transparency is preserved when possible.
Why does WhatsApp still compress my image after I compress it?
WhatsApp re-compresses images above ~1 MB. Use our WhatsApp preset (quality 60%) to get under 1 MB — this prevents WhatsApp from applying any further compression.
Can I compress multiple images at once?
Yes. Click the browse button and select multiple files, or drag and drop several images at once. Each file is compressed and available to download individually.
Can I convert JPG to PPT or PPTX?
Yes. After compressing your images, click "Download All in PPTX" to convert your JPG and PNG images into a PowerPoint presentation. Each image is placed on its own widescreen slide, so you get a ready-to-present PPTX file in one click — no Office or upload required.
How do I convert images to PDF?
Compress or add your images, then click "Download All in PDF". The tool builds a single PDF with one image per page (portrait by default, with an optional landscape mode). It works entirely in your browser, so your pictures are never uploaded.
Can I convert PNG to PPT?
Yes. PNG, JPG and other common image formats are supported. Add your PNG files, then use "Download All in PPTX" to turn them into a PowerPoint, or "Download All in PDF" to combine them into a PDF.
How do I compress images to PPT or PDF?
First compress your photos to your chosen quality, then export them with "Download All in PPTX" or "Download All in PDF". You get smaller, optimised images already packaged into a PowerPoint or PDF — ideal for reports, slideshows and email attachments.
Is this JPG to PowerPoint and JPG to PDF converter free?
Completely free, with no sign-up and no watermarks. Compressing images and converting JPG or PNG to PPT, PPTX or PDF all run locally in your browser, so nothing is sent to a server.
