Modern phone cameras shoot 4–8 MB photos by default, sometimes 12 MB on higher-end devices, and websites, email systems, and government upload portals routinely reject anything over 1–2 MB. Our free online image compressor squeezes JPEG, PNG, and WebP images down to whatever target size you need, with a live quality preview so you can see exactly how much detail you are trading away before you download. Drop the image in, slide the quality slider until the file size hits your target (the calculator shows the result in real time), optionally cap the width to shrink very large images further, and download. The compression engine uses the HTML5 Canvas API directly in your browser — your photos never travel to any server, which matters when the image is a passport scan, a leaked screenshot, a confidential document photo, or anything else you would not want sitting on a stranger's machine. Common workflows people run it through: shrinking phone photos to fit the under-100 KB limit on UPSC, SSC, NEET, JEE, IBPS, and other Indian government exam application forms, optimising hero images and product photos for WordPress and Shopify storefronts where every kilobyte slows page load and hurts SEO, fitting profile photos and ID scans inside the strict size limits on visa, passport, and driving-licence portals, compressing receipts and expense screenshots before bulk-uploading to QuickBooks/Expensify, and trimming gallery photos before sending them via WhatsApp or email where carriers degrade larger attachments anyway. Typical compression results: a 4 MB iPhone photo at 80% quality lands around 600–800 KB with no visible quality loss; the same photo at 60% drops to 250–350 KB with very mild artefacts in solid-colour areas; PNG screenshots see 50–70% reductions. For PDFs, use our [PDF Compressor](/tools/compress-pdf) instead, and for cropping or aspect-ratio changes use the [Image Resize](/tools/resize-image) tool. Need to convert formats while compressing? Try [PNG to JPG](/tools/png-to-jpg) or [JPG to PNG](/tools/jpg-to-png).

How to Use Image Compressor

Upload Your Image

Drag and drop your JPEG, PNG, or WebP image into the upload area. Files up to 50 MB are supported. Multiple files can be processed one after another.

Adjust Compression

Set the quality level from 10% to 100% — 80% is a sweet spot for photos with no visible loss, 60–70% works for casual sharing. Optionally cap the maximum width to shrink oversized images further.

Compress & Download

Click "Compress Image" and watch the original-vs-compressed size comparison. Download the optimized file instantly. The processing runs locally — nothing is uploaded.

Features

Smart Compression

Canvas-based compression reduces file size while maintaining excellent visual quality. The encoder picks the best chroma subsampling and entropy coding for each image automatically.

Quality Control

Precise quality slider from 10% to 100%. Preview the compressed file size before downloading so you can dial in the exact target without guesswork.

Size Comparison

See original vs compressed file sizes side by side with the exact reduction percentage. Useful when you have a hard size cap to hit (under 100 KB, under 1 MB, etc.).

Max Width Setting

Set a maximum width to automatically resize oversized images during compression — a 4000-pixel-wide phone photo gets cut to 1920 or 1280 pixels with one click.

Format Support

Accepts JPEG, PNG, and WebP input. Output is JPEG (best compression for photos) or the original format depending on the source. EXIF metadata is stripped for privacy.

Browser-Based & Private

Compression runs entirely in your browser using the HTML5 Canvas API. Your photos never travel to any server, never get logged, never get cached anywhere outside your device.

Frequently Asked Questions

Typical photos compress 40–60% at 90% quality with absolutely no visible difference, 60–80% at 80% quality with imperceptible loss for most viewers, and 80–90% at 60–70% quality with mild artefacts in flat-colour areas like sky or skin. Screenshots and graphics with sharp edges compress less aggressively because the encoder sees more detail to preserve. The size-vs-quality trade-off is shown live as you slide.

Input: JPEG (.jpg, .jpeg), PNG (.png), and WebP (.webp). Output: JPEG by default (best compression for photographic content) with the option to keep PNG for screenshots and graphics that need lossless compression. For modern web use, consider converting to WebP — it beats both JPEG and PNG on file size at equal quality.

Yes — Indian exam portals (UPSC, SSC, NEET, JEE, IBPS, RRB) typically require photos under 100 KB and signatures under 50 KB at specific dimensions like 4.5 × 3.5 cm or 200 × 230 pixels. Set the quality slider to 60–70% and cap the max width at 240 pixels for a typical photo. The size meter shows when you are under the cap. Test on a low-traffic page of the portal first to make sure the dimensions match.

For most photographic content (selfies, landscapes, product shots), 80% quality is visually indistinguishable from the original at normal viewing distance. The differences only show up in very specific edge cases — pure-colour gradients in sky shots, fine text rendered as part of an image, or extremely high-detail textures. For everyday use, 80% is the recommended default.

No. The entire compressor runs as JavaScript inside your browser using the HTML5 Canvas API. Your photos never leave your device — they are not uploaded, not logged, not cached anywhere outside your browser, and not visible to anyone except you. Once you close the tab, the photo data is discarded entirely. This matters especially for passport scans, ID cards, salary slips, and any other document you would not want on a third-party server.

No. The compressor strips EXIF metadata when it re-encodes the image, which is actually a privacy benefit — phone photos contain GPS coordinates, the exact time taken, and camera serial numbers, which most people do not want to share when posting to forums, social media, or marketplaces. If you need EXIF preserved (for camera workflow or photography), use a desktop tool like ImageOptim or jpegoptim instead.

You can compress images one after another quickly — drop one, download the compressed version, drop the next. There is no per-session limit. For true batch processing of dozens of files, command-line tools like ImageMagick or jpegoptim are more efficient because they automate the loop, but for everyday compression of 5–20 images this tool is faster than any setup.

WhatsApp and most social platforms force aggressive compression on every photo you send, often dropping quality to 50% or lower with no control on your side. Using this compressor first lets you choose the exact quality you want — so a recipient receives your already-optimised version rather than the platform's heavily-recompressed one. This is especially useful for businesses sharing product photos or designers sending portfolio samples.
