Free image compressor
Shrink images to a target size or preset. Batch several files in your browser — no upload wait — then download a ZIP. Files never leave this device.
Click to choose images, or drag them here
JPG, PNG, WebP, GIF, SVG · up to 50 files · max 40 MB each
How small should files get?
The tool finds the highest quality that still meets the target size, and scales down only if needed. Images already under the limit are left unchanged.
How it works
Step 1 · Add files
Drop JPG, PNG, WebP, GIF, or SVG into the drop zone above (up to 50 files).
Step 2 · Confirm settings
Pick a size preset (3MB / 2MB / 1MB) or set a custom KB/MB target; optionally change output format.
Step 3 · Download
Download one file or the whole batch as a ZIP — use Compare or Adjust on a result if quality or size needs a tweak.
Good for
- Hitting an exact KB/MB cap for email, forms, or a CMS
- Batch-shrinking a folder and downloading one ZIP
- Keeping originals on your computer — nothing is uploaded
What to watch for
Pick a dedicated size page when the instructions say “under 200KB” or similar. PNG photos that will not shrink should switch output to JPEG or WebP. Compare/Adjust one file instead of redoing the whole batch.

|---|---|---|
| Where compression runs | In your browser — nothing is uploadedYes — | Uploaded, processed, then downloadedNo — |
| Target size | Presets plus custom KB/MB limitsYes — | Often quality-only, or locked behind signupNo — |
| Batch work | Compress many files and download a ZIP — no upload waitYes — | One file at a time, or hit daily free-tier caps; ZIP often needs signupNo — |
| Privacy | We never see your photosYes — | Depends on that site's policyNo — |
| Already small enough | Files under the limit are left unchangedYes — | May recompress everything anywayNo — |

Frequently asked questions
Do you upload my images?
No. Compression happens in your browser only — files never leave your device. See the Privacy page for how local processing works and what we do not store.
Which formats are supported?
Open JPG, PNG, WebP, GIF, and SVG. Export JPG, PNG, or WebP. GIF uses the first frame; SVG is rasterized. Camera RAW (for example PEF) is not supported.
Can I compress to exactly 200KB?
Yes — use Custom target size, or open a dedicated Compress to 200KB page. If a photo-like PNG will not shrink enough, switch output to JPEG or WebP.
What if I miss my size target?
Lower max width, change output format, or pick a dedicated KB/MB page. On any result row, open Compare to check quality vs size, or Adjust to re-run that image with different settings.
What do Compare and Adjust do?
Compare opens a before/after preview with file sizes. Adjust lets you re-compress one image — change quality, target size, or max width — without redoing the whole batch.
Can I compress many images at once?
Yes. Drop a batch (up to 50 files · max 40 mb each), process locally with no upload wait, then download each file or all results as a ZIP.
