To compress an image to 1 MB (1,048,576 bytes) for free, drop it into SammaPix Compress and adjust the quality slider until the output meets the target — for most photos, quality 75-90% reaches 1 MB. Processing happens 100% in your browser using the Canvas API — no upload, no signup, no watermark. Tested on 100 real images: SammaPix matched SSIMULACRA 2 quality scores above 65 (no visible loss) at all output sizes >= 50 KB. For sizes below 25 KB, expect visible compression artifacts on photographic content — vector-style images and screenshots fare best.
Open the SammaPix Compress tool and drag your image into the drop zone. Supports JPEG, PNG, WebP, and GIF.
Adjust the quality slider until the output size is at or below 1 MB. Lower quality = smaller file.
Download your compressed image instantly. Everything runs in your browser — your photos never leave your device.

At 1 MB you can maintain full-resolution (3000+ px) images at quality 90%+ — virtually indistinguishable from the original.
Use 1 MB as the upper limit for retina hero images on image-heavy sites like photography portfolios.
For print preview workflows, 1 MB provides enough detail for A4 prints at 150 DPI.
Pair 1 MB images with lazy loading and a CDN to ensure fast delivery despite the larger file size.

Use Compress to reduce your images to 1 MB or below, or Convert to WebP for even smaller files at the same quality.
Upload to SammaPix Compress and set quality to 85-90%. A typical 12 MP smartphone photo (4000×3000 px) compresses to around 1 MB at quality 85%. If it is still too large, reduce to 3000 px wide first.
For most web pages, yes — aim for 100-200 KB per image. However, 1 MB is appropriate for hero banners on portfolio sites, full-screen photography galleries, or product zoom views. Always use lazy loading for 1 MB images.
WebP at 1 MB is roughly equivalent to a 2 MB JPEG in visual quality. If your audience uses modern browsers, WebP is the best choice. For maximum compatibility, JPEG at quality 85% is reliable.
RAW files (20-60 MB) must first be exported as JPEG or WebP, then compressed. Export at full resolution in JPEG, then use SammaPix to compress to 1 MB. The result retains excellent detail for web viewing.
