Compress vs resize — pick the right lever

Compress lowers quality or encoding efficiency so the same dimensions take fewer kilobytes. If a portal says “max 200 KB” or “under 1 MB,” start here. If it says “max 2000×2000 pixels,” resize first, then compress.

How to hit a target size

Use the quality slider for gradual savings, or open a preset like compress to 50 KB / 100 KB when a site documents an exact limit. Photos tolerate more compression than screenshots with tiny text — watch the live preview before you download.

Format choices that save space

  • JPG — best default for camera photos.
  • WebP — usually smaller than JPG at similar quality when the destination accepts it.
  • PNG — keep for graphics with sharp edges or transparency; compressing PNG helps less than converting photos to JPG/WebP.

What we never do

No forced watermark, no signup wall, and no permanent storage of files you only download. Share links are temporary and covered in our privacy policy.

Frequently Asked Questions

Mild compression is hard to notice on social uploads. Heavy compression softens fine detail — lower quality gradually and compare the preview.
Yes — use target-size tools (50 KB, 100 KB, 200 KB, 1 MB) or adjust quality until the estimated size fits.
Yes. Upload from your camera roll, compress, then download or share from the same mobile browser.
PNG re-encoding can still reduce bytes; for maximum savings on photos, convert to JPG or WebP after you are happy with the look.
No. Editing stays in the browser until you tap Share. Download never requires an upload.
Typical compression reduces file sizes by 50-90% depending on the original format and content. Photos with lots of detail compress to around 60-70% reduction, while simpler graphics can achieve 80-90% reduction.
Our default quality settings are carefully tuned to be visually lossless — most people cannot tell the difference. You can adjust the quality slider if you need even smaller files or want to prioritize sharpness.
Lossy compression (JPG, WebP) discards some data to achieve smaller files. Lossless compression (PNG) reduces size without any data loss. We support both and recommend lossy for photos and lossless for graphics with text or sharp edges.
