Image editing help

Peekless Image compresses, resizes and converts images and removes the location and other metadata from photos. All right in your browser – files are never uploaded.

Getting started

1. Add images: drag them into the window, click Choose images, or paste a screenshot with Ctrl+V. You can add as many as you like at once.
2. Pick an edit in the Compress, Resize, Convert or Metadata tab and set it up. It applies to all images in the list.
3. Process them with the button below. You’ll see the new size and dimensions of every image.
4. Download images one by one, or all at once in a ZIP. On a phone you can share them directly.

If you change the settings, just process the images again. Your browser remembers the settings for next time.

Compress

Quality sets how much a photo shrinks: lower quality means a smaller file. Values of 75–85 usually look the same as the original. If you check At most and enter a size in KB, the tool finds the highest quality that fits – handy for forms with an upload limit. If even the lowest quality isn’t enough, the dimensions are reduced too.

If the compressed image would be bigger than the original (it happens with photos that are already well compressed), we keep the original, just without metadata. PNG is compressed without losing quality; for a much smaller file, convert it to JPG or WebP.

Resize

Enter the size as the longer side, width, height, percent, or a box the image should fit in. The aspect ratio is kept. Smaller images aren’t enlarged unless you check Enlarge smaller images too. We use the high-quality Lanczos filter for both shrinking and enlarging.

Convert format

• JPG – for photos. Small files that every program opens. No transparency: transparent areas turn white.
• PNG – for graphics, logos and screenshots. Lossless and supports transparency; large for photos.
• WebP – for the web. Smaller than JPG at the same quality and supports transparency. At quality 100 it’s saved losslessly.

We can open JPG, PNG, WebP, HEIC and HEIF (iPhone photos), AVIF, GIF and BMP. We convert HEIC even in browsers that can’t open it themselves. From an animated GIF or WebP, the first frame is converted.

Metadata and location

Phone photos usually carry the exact GPS location, date and time, the device model and a thumbnail. Photos with a location show a Location label. Every kind of processing removes the metadata: EXIF, XMP, IPTC, comments and data stored after the image (such as the video of Motion Photos).

In the Metadata tab, JPG, PNG and WebP lose only their metadata and the image stays byte for byte the same. Other formats (HEIC…) are converted to JPG. Under More options you can keep the capture date and camera – never the location. We keep the photo’s color profile so its colors don’t change.

Large photos and phones

Images are processed in your device’s memory. On a computer we handle photos of over 48 megapixels; on an iPhone, photos larger than 16 megapixels are processed slightly scaled down because Safari doesn’t allow more. A single file can be up to 200 MB. If memory runs low, close other tabs or process fewer images at once.

Privacy

Images are never uploaded – your browser processes them and the results stay with you. We use no cookies and no tracking. See the privacy policy for details.
