Common questions about image formats, compression and browser-based image tools.
JPG is the standard choice for photographs. It uses lossy compression that works well for complex color gradients. WebP is a modern alternative that offers better compression at similar quality. PNG is better for screenshots, logos and images with transparency.
Lossy compression (JPG, WebP lossy) permanently removes some image data to reduce file size. The result looks similar but is not identical to the original. Lossless compression (PNG, WebP lossless) reduces file size without discarding any data - the decompressed result is identical to the original.
Use one of the targeted compression tools: Compress to 20KB, 50KB, 100KB or 200KB. These tools adjust quality and dimensions to hit the target size. For very small targets, the image dimensions may also need to be reduced.
Converting PNG to JPG applies lossy compression, which can introduce artifacts especially in areas with sharp edges, text or flat colors. The degree of quality loss depends on the JPG quality setting. Converting back from JPG to PNG does not recover the lost detail.
Yes. The HEIC to JPG converter processes HEIC files locally in your browser. Support depends on your browser - Chrome and Edge generally support HEIC decoding. If your browser does not support HEIC, try a different browser.
No. All image tools process files locally in your browser using the Canvas API. Your images are not sent to NEXDOWNLOAD servers. The converted or compressed result is generated on your device and downloaded directly.
It depends on the platform. Instagram feed posts work best at 1080x1080 (square) or 1080x1350 (portrait). YouTube thumbnails should be 1280x720. Facebook covers are 820x312. Use the Social Image Resizer or platform-specific tools for the correct dimensions.

Compare the extracted swatches with the image in context. For brand work, verify official color specifications instead of assuming an automatically sampled color is the approved brand value.
Strip EXIF data and GPS location from photos. Use it when you need removing embedded camera and location metadata before a photo is shared. Inspect the exported file with a metadata viewer if privacy is important. Also open the image normally to confirm orientation and visual appearance were preserved.

Resize images to any custom width and height in pixels.
Use it when you need matching pixel dimensions and aspect ratios required by websites, social platforms and upload forms. Resizing changes pixel dimensions. Depending on the target shape, the workflow may crop, fit or pad the source rather than stretching it. File size can change as a side effect, but resizing and compression are not the same operation.

Create .ico and PNG favicons from any image or logo.
Use it when you need turning a logo or simple image into small favicon assets for websites. The artwork is resampled to small square sizes. Fine text and thin detail can disappear, so a simplified mark often works better than a full horizontal logo.
Before you finish, Preview the result at actual browser-tab size, not only enlarged. Check transparent edges, centering and contrast on both light and dark browser chrome.
Extract the dominant color palette from any image.
Use it when you need sampling dominant colors from an image for design, branding and interface work. The source image is analyzed rather than rewritten. The output is a set of representative color values, so similar shades may be grouped and tiny accent colors may not appear among the dominant results.
Before you finish, Compare the extracted swatches with the image in context. For brand work, verify official color specifications instead of assuming an automatically sampled color is the approved brand value.
Strip EXIF data and GPS location from photos.
Use it when you need removing embedded camera and location metadata before a photo is shared. The visible pixels are intended to remain the same while metadata fields are removed from the exported copy. Keep the original if you may later need capture date, camera settings or location information.
Before you finish, Inspect the exported file with a metadata viewer if privacy is important. Also open the image normally to confirm orientation and visual appearance were preserved.
