Auto compress · adjustableFree Online Image Compressor for JPG, PNG, and WebP
Camera and screenshot exports are often far too large for email, chat, or website uploads. This image compressor runs in your browser — upload, use auto compress or set your own size cap, crop, preview, and download without sending the file to a cloud server.
Auto compress is on by default and balances quality with a smaller file. Uncheck Auto in the compress panel when a form, CMS, or email gateway names an exact kilobyte limit.
When You Need a General Image Compressor
Use this when you want a flexible compressor — not a page locked to one portal size.
What Image Looks Like on Disk

Crop to the panel you need before compressing.

Why JPG Is the Default for Photo Compression
Most email clients, CMS media libraries, and social platforms expect JPG for photographic content.
Smaller than PNG for photos
Lossy JPG fits natural scenes into tighter byte budgets.
Universal acceptance
Email, WordPress, and legacy portals rarely block JPG.
Fast re-export
Any editor or phone can save JPG for quick recompress.

JPG, PNG, or WebP — Which to Pick
PNG
- Ink signatures on white paper
- Stamps and line drawings
- Logos needing transparency
Heads-up: Full-color PNG photos often stay large until you resize the canvas aggressively.
WebP
- Modern web upload widgets
- Android-heavy portals
- Re-saving an already compressed shot
Why try it: WebP can beat JPG on byte count when your CMS or app accepts it.
PNG helps logos and UI captures with transparency — photos are usually smaller as JPG.
What Changes at Image
Text overlays and faces should stay readable at the size you will display — not at full camera resolution.
Works well
- Blog hero
- Product photo
Sharp at column width.
Usually OK
- Indoor scene
- Light grain
Fine for email embed.
Hard fit
- Full desktop screenshot
Crop to the relevant panel.
Three Things That Save a Rejected Upload
When to Use This Image Compressor
Use this page when you need a flexible compressor — switch to a size-specific tool only when the form prints an exact kilobyte cap.
- Email bounce — Attachment exceeds provider limit
- CMS warning — Media library rejects large upload
- Unknown KB cap — Site says smaller file without a number
- Exact 100KB rule — Open the dedicated 100KB compressor
- JPEG-only form — Try the JPEG compressor page
Practical Compression Tips
1920 px wide
Common hero width before KB tuning.
Remove dead space
Gray margins inflate size for no benefit.
Check size on disk
Right-click the download — confirm KB before attach.
Readable text overlays
Compress after adding headlines on heroes.
Even lighting
Underexposed photos compress with muddy faces.
Try a size-specific tool
100KB and 50KB pages include portal examples.
JPG, PNG, or WebP at Image?
Pick the format your destination accepts — not the one that looked best in your editor.
| Format | Best for | At Image | Difficulty |
|---|---|---|---|
| JPG | Photos, email, CMS | Default for most uploads. | Easy |
| WebP | Modern CMS and apps | Often smaller at same quality. | Very Easy |
| PNG | Logos, UI captures | Use when transparency is required. | Moderate |
Example Upload Limits This Tool Helps With
Every site writes its own rules — treat these as patterns from real forms, not promises.
Common Image Compression Mistakes
Still too large
Lower width first — then quality.
Wrong format rejected
Switch to JPG when PNG fails validation.
Theme crops badly
Match featured image dimensions before upload.
Text unreadable
Resize canvas — do not crush quality alone.
Upload timeout
Compress locally — raw camera files stall on mobile data.
