Image Compressor
Drop in a photo and compress it locally — WebP first with automatic JPEG fallback, adjustable quality; phone photos shrink to shareable sizes.
>_ USAGE GUIDE
Drop in a photo (or click to choose one) and local compression finishes instantly, with the before-and-after file sizes shown side by side. WebP is preferred by default — at equal visual quality it typically lands 25–35% smaller than JPEG — with automatic fallback to JPEG whenever the browser lacks WebP support, so you always get a result. The quality slider adjusts live: keep going until the size fits your target, and phone photos usually compress with no visible difference.
- Drop the photo in: compression starts immediately, no upload
- Adjust quality: around 70 favors size, 85+ favors fidelity
- Download the result: the compressed file saves locally, ready to send or upload
Typical scenarios: a photo too large for a chat app or email attachment, website images dragging down page load, and upload forms with a few-MB limit. One pass usually cuts the size by more than half.
Compression runs entirely in your browser — photos are never uploaded to any server. ID photos and family pictures can be processed with confidence, an assurance most online compressors cannot give.
>_ FAQ
Q1 · Will compression visibly degrade the photo?
Lossy formats (WebP/JPEG) at quality 75–85 are effectively indistinguishable from the original by eye while cutting size by more than half. Use the live slider to decide: around 70 when size is the goal, 85+ when fidelity is. Compression is one-directional — keep the original backed up and re-compress from it when needed.
Q2 · WebP or JPEG — which should I choose?
WebP is the newer format: smaller at equal quality and it supports transparency. JPEG is the most universally compatible format in existence. Prefer WebP by default and fall back to JPEG only when the target platform explicitly rejects it. PNG remains the right choice for screenshots and icons that need lossless pixels or a transparent background; for photos, WebP/JPEG wins on size.
Q3 · My phone photo is too large to send — what do I do?
Modern phones produce 3–8 MB per shot while chat apps, email, and forms commonly cap at 1–10 MB. Drop the photo in and the default settings already bring it to a few hundred KB with no perceptible loss; if it still exceeds the limit, move the quality slider one step left and compress again.
Q4 · Are my photos uploaded to a server?
No. Compression uses the browser's Canvas capability on your own machine — zero bytes uploaded, nothing stored. It even works offline. Privacy-sensitive photos can be processed without a second thought.
Q5 · Why did a PNG sometimes get bigger after compression?
PNG is a lossless format that is already compressed internally. Converting it to lossy WebP/JPEG usually shrinks it dramatically — but if the original PNG has very few colors (flat icons, simple screenshots), lossy encoding can end up larger or introduce artifacts. Keep such images as PNG, or use the Image Converter for format-specific handling.
