Clear, hands-on guidance for reducing image, video, and PDF file size in your browser.
PDF size usually comes from images, scans, embedded fonts, and duplicated objects. Start with balanced compression, check text selection and links, and use local processing for sensitive documents instead of uploading them to an unknown service.
PNG remains the safest exact and compatibility format, while lossless or lossy WebP can reduce web bytes. Choose by edge fidelity, destination support, and the type of transparent image.
PNG to WebP is useful for many web graphics and photo-like PNGs, but tiny icons and already optimized assets may not shrink. Convert a copy and measure the real output.
Make a copy, remove EXIF, GPS, IPTC, XMP, and embedded thumbnails locally when privacy matters, then verify the exported file with a metadata viewer. Keep the original and review visible clues separately.
AVIF often wins on photographic compression while WebP is easier to encode and broadly supported. Learn when to serve each format and how to verify the trade-off.
WebP often reduces bytes for web photos, while JPEG remains the safest compatibility format. Use a measured conversion workflow instead of treating one extension as the universal answer.
Choose JPEG, PNG, WebP, or AVIF by image content and delivery constraints, then verify the actual file size and visual result instead of trusting a universal winner.
Use the original as a master, resize only to the largest useful display size, select a format for the image content, and inspect the exported file before replacing anything.
