Shrink an Image for Sharing

Shrink a photo for sharing in one step

Phone photos are huge — a modern camera shot can be 5–12 MB, more than messaging apps, email, and web forms want to carry, and every one of them still holds the GPS coordinates and camera details baked in by your phone. This tool does the three things you actually want before sharing, in a single pass:

1. Downscale the longest side to a size that still looks sharp on a phone or in a browser (default 1600 px), keeping the aspect ratio and never upscaling.
2. Strip the metadata — EXIF, GPS location, timestamps and comments — so you are not leaking where and when the photo was taken.
3. Compress by re-encoding at your chosen quality, optionally converting to a lighter format (JPEG or WebP shrink photos the most).

Everything runs locally in your browser with WebAssembly ffmpeg. Nothing is uploaded to a server.

Worked example

Take a 4032 × 3024 JPEG straight off a phone (about 4.8 MB, with GPS EXIF). With Max size = 1600, Quality = 80, Format = JPEG, and Strip metadata = on, the result is a 1600 × 1200 JPEG of roughly 250–400 KB with no EXIF or GPS — a ~90% smaller file that is still crisp for chat or a web upload. Set Max size = 0 to keep the original dimensions and only compress + strip.

Presets

The chips under the inputs are one-click starting points: Messaging (1600 px JPEG), Story / vertical (1080 px WebP), Email friendly (1024 px JPEG), and Just compress (keep the original size, quality 70). Adjust any field afterwards.

Limits and edge cases

• Supported formats: JPG/JPEG, PNG and WebP for both input and output. HEIC and other formats are not decoded here — convert them first.
• Longest-side cap: Max size caps the longer of width/height; the shorter side scales proportionally. A smaller image is never enlarged. Output dimensions are rounded to even numbers so JPEG always encodes cleanly.
• PNG quality: PNG is lossless, so on PNG the quality slider only changes how hard the encoder works (higher effort → smaller file), not the pixels. To make a photo-heavy PNG much smaller, convert it to JPEG or WebP.
• Transparency + JPEG: JPEG has no alpha channel, so converting a transparent PNG to JPEG fills the transparent areas with black. Keep PNG or choose WebP to preserve transparency.
• Orientation: stripping metadata removes the EXIF orientation flag. Photos whose rotation is already baked into the pixels are unaffected; if a phone photo comes out rotated, re-save it with orientation applied first.
• True "compress to exactly 200 KB": not offered — hitting an exact byte target needs an iterative quality search. Use the quality and max-size sliders to trade size against sharpness.
