Compress an image online without visibly losing quality — and without uploading it anywhere. PIXLFLW re-encodes your photo locally in your browser with an adjustable quality slider and a live file-size preview, so you can hit a target like «under 200 KB» precisely instead of guessing.
How to get the smallest file
- Lower the JPG quality — quality 70–80% is usually visually indistinguishable from the original at a fraction of the size.
- Resize down first — a 4000-pixel-wide photo shown at 800 pixels wastes megabytes; add a resize step before export.
- Pick the right format — photos compress best as JPG; graphics with few colors stay small as PNG.
- Watch the size preview — the export dialog shows the estimated file size for the current settings before you save.
How to compress a photo
- Drop an image into the upload area above (formats: GIF, JPG, BMP, PNG, WEBP, HEIC, TIFF).
- Optionally add a resize step to reduce the dimensions.
- Click Download, choose JPG, and drag the quality slider until the previewed size fits your limit — then save.
Everything runs on your device: compressing private documents, IDs or medical scans here is safe because the files are never uploaded to any server.
