Free TinyJPG Alternative: Compress JPG Photos

Photos from phones and cameras are usually saved at a very high JPEG quality, often 90 or more, plus several kilobytes of metadata. That is useful for editing but wasteful for sharing and publishing. Re-encoding at a moderate quality removes detail the eye barely notices and can cut the file to a fraction of its size. That is the idea behind services such as TinyJPG, and this page offers the same kind of JPEG compression for free, directly in your browser.

JPG and JPEG files go in and JPG files come out, re-encoded at quality 75 by default with the original dimensions kept. Camera orientation is applied before encoding, so portrait photos stay upright, and EXIF data such as GPS position and camera model is removed. WoowTools is independent and not affiliated with TinyJPG; the name only describes the kind of compression.

How to use the TinyJPG Alternative: Smart JPEG Optimizer

1. Drop your images onto the upload area, click it to choose files, or paste an image with Ctrl+V. This page accepts JPG and JPEG files, many at once and up to 80 MB each.
2. Adjust the quality slider: 75 is a solid default for web and email, 80 to 85 suits portfolio images, and 60 to 70 is fine for thumbnails and previews.
3. If a site demands a maximum size, switch to Target size: the optimizer searches for the highest quality under your limit and only reduces the dimensions if quality alone is not enough.
4. Check the result with the before/after slider: drag the divider across the preview and read the new dimensions, file size, quality and percentage saved underneath. Any change to the settings re-processes every image automatically.
5. Download a single image, or use Download all (ZIP) for the whole batch. Under More options you can also set a DPI value and a file-name pattern with {name}, {w} and {h}.

Getting the most from JPEG compression

• Compress once, from the original. Every JPEG re-save loses a little more; start from the camera file rather than an image that has already been compressed.
• Resize when you can. A 4000-pixel photo shown at 1200 pixels wastes most of its bytes; open Resize and choose Max for a much bigger saving.
• Exact upload limits. Pages like compress image to 100KB are preset for common limits, and the JPG compressor offers the same engine with other defaults.
• Even smaller files. If JPG is not a requirement, JPG to WebP usually produces smaller files at the same visual quality.

There is no daily quota or file-count limit: the work is done by your own device, so the only practical limit is its memory, with files of up to 80 MB accepted.

Private, free and fast

The whole job runs in your browser: images are decoded, resized and re-encoded on your own device, so nothing is uploaded to a server. There is no sign-up, no watermark and no daily limit, and location and camera data (EXIF) are removed from every result.
