📖 Guide & FAQ

🗜️ How to Compress an Image

  • 1 Click the upload zone or drag & drop up to 50 images (JPG, PNG, WebP — max 100 MB each).
  • 2 Set your Target Size in KB. Default is 50 KB — adjust to any value you need.
  • 3 Optionally set a Max Width and Max Height to resize the output dimensions.
  • 4 Choose your preferred dimension unit — Pixels, MM, or CM. The tool auto-converts at 96 DPI.
  • 5 Click Compress. The tool runs a precision binary search across quality levels to match your target file size.
  • 6 Once done, the result card appears showing original size, compressed size, and reduction %. Click Download to save.

💡 Tips

  • ✦ For very small targets (e.g. 20 KB), setting a Max Width can significantly help — smaller dimensions = smaller file.
  • ✦ PNG files are converted to JPEG during compression, which gives much better size reduction.
  • ✦ All processing happens in your browser — no image is ever uploaded to a server.

✂️ How to Crop an Image

  • 1 Switch to the Crop tab and upload your image by clicking or dragging it into the zone.
  • 2 A blue selection box appears over your image. This is your crop area.
  • 3 Drag the box to reposition it anywhere on the image.
  • 4 Pull the handles (the 8 dots around the box) to resize the crop area — corners resize both axes, edge handles resize one axis.
  • 5 The live badge inside the box shows the exact pixel dimensions of your selection.
  • 6 Click Apply Crop to cut the selected region. The preview updates instantly.
  • 7 Click Download to save the cropped image as a JPEG.

💡 Tips

  • ✦ You can apply crop multiple times — each crop works on the current image state.
  • ✦ Touch/mobile is fully supported — drag and resize handles work with your finger.
  • ✦ Click the × button to clear the image and start over.

❓ Frequently Asked Questions

No. Everything runs 100% in your browser using the Canvas API. Your images never leave your device and no data is sent anywhere.
You can upload JPG, PNG, and WebP images. Output is always saved as JPEG for maximum compression efficiency. Files up to 100 MB are supported.
Yes — the tool uses a 14-step binary search across JPEG quality levels to get as close to your target size as possible. Results are typically within 1–3% of the target.
They control the unit for Max Width and Max Height fields. Pixels is direct screen pixels. MM and CM are physical print units converted at 96 DPI (1mm ≈ 3.78px, 1cm ≈ 37.8px). Switching units auto-converts any values you've already entered.
JPEG compression is lossy — at lower quality levels, some fine detail is reduced to achieve smaller file sizes. For most images compressed to 50 KB+, the quality difference is barely noticeable.
You can select or drop up to 50 images at once. Each image is processed individually using the same settings.
Not in a single step yet, but you can: crop your image in the Crop tab → download it → then upload that downloaded file into the Compress tab to apply compression.
