Modern format · ~30% smaller than JPG at equal quality.
What this does
Drop in any image, pick a target format, set quality, download. Modern formats like WebP and AVIF cut file size 30–80% over JPG at the same visual quality. Runs in your browser using Canvas — no upload, no quality theft.
JPG, PNG, WebP, GIF, BMP, or HEIC. The current format and file size show automatically.
JPG for photos going to email or older systems. PNG when you need transparency or sharp graphics. WebP for modern web hosting (40% smaller than JPG). AVIF for cutting-edge web (50% smaller than WebP, but only widely supported since 2023).
Quality 75–85 is the sweet spot for JPG/WebP/AVIF — significant compression with no visible loss. PNG is lossless so quality slider doesn't apply. Hit convert and download.
File sizes from a 1920×1280 product photo. AVIF wins on file size by a wide margin, but support varies — pick based on where the image lives, not on size alone.

The rule of thumb
Photos → WebP for web, JPG for email and older clients. Graphics with text/transparency → PNG. Modern web that can fall back → AVIF with JPG/WebP fallback for older browsers.
Privacy
Image converters that upload to a server can re-compress aggressively, strip metadata you wanted to keep, or worse — log your files. Our converter uses the browser's native Canvas API for conversion. No upload, no quality games, no logging.
Web
Modern browsers all support WebP. A 200 KB JPG becomes a 90 KB WebP at the same visual quality. Cuts page weight, helps Core Web Vitals.
Compatibility
iPhone shoots HEIC by default. Windows users, older Macs, and email clients often can't open HEIC. Convert to JPG before sharing.
Transparency
JPG doesn't support transparency. If you've isolated a product on a background, save as PNG so the transparency is preserved.
Design
Designer-exported PNGs at 4 MB each fill up email inboxes. Converting to JPG cuts file size by 70%+ with no client-visible loss.
Vector-to-raster
Modern docs sites support WebP and AVIF. Save your screenshots in WebP from the start — smaller repos, faster page loads.
Some print services only accept JPG or TIFF. Convert before upload to avoid rejection or auto-conversion (which often re-compresses).

Each format has a strength. Picking the right one matters more than file-size obsession.
JPG / JPEG
Best for: Photos, email attachments, anywhere transparency isn't needed
Watch out: Lossy — re-saving repeatedly degrades quality. Edit in PNG, export to JPG once.
PNG
Best for: Logos, icons, screenshots with text, anything with transparency
Watch out: Photos as PNG are typically 5x larger than JPG with no visible benefit.
WebP
Best for: Modern web — 30–40% smaller than JPG at same visual quality, supports transparency
Watch out: Email clients (Outlook) and older systems may not display. Use for web first.
AVIF
Best for: Cutting-edge web — 50% smaller than WebP, supports HDR
Watch out: Safari only added support in 2022. Older browsers fall back to placeholder unless you provide JPG fallback.
GIF
Best for: Short animations under 5 seconds, low-color graphics
Watch out: Terrible for photos (limited to 256 colors). For modern animations, MP4 or WebP both work better.
HEIC
Best for: iPhone storage — Apple's compressed format saves ~50% over JPG
Watch out: Limited compatibility outside Apple ecosystem. Convert to JPG before sharing widely.
Don't convert a 75-quality JPG to WebP — you're encoding compression artifacts as if they were real detail. Start from the original PNG or RAW if you still have it.
PNG is lossless, but lossless doesn't mean small. A 4000x3000 photo at 4 MB as JPG is often 25 MB+ as PNG. Lossless only matters when every pixel exact value matters (medical scans, icons).
If you're using WebP/AVIF in email signatures or HTML email, provide a JPG fallback. Outlook 2019 and older corporate Outlook installs still don't decode them.
JPG/WebP at quality 80 is indistinguishable from 100 in blind tests, with 50%+ file-size savings. Below 70, blocking artifacts start appearing in flat areas like sky or skin.
Each lossy conversion (JPG → WebP → JPG) compounds compression damage. If you might need multiple formats, keep the original PNG or high-quality JPG as a master and convert from that.

Image Resizer
Resize dimensions in the same workflow — often paired with format conversion.
HEIC to PDF Converter
If your source is HEIC and target is PDF, skip the JPG step.
EXIF Remover
Strip metadata without re-encoding — preserves original quality.
Compression savings estimator
Estimate WebP/AVIF savings across a folder before bulk-converting.
Everything runs locally in this tab. Nothing uploads, nothing stores on a server, nothing indexes.
No progress bars stuck at 99%, no rate limits, no 'please wait' screens. Drop, click, done.
When the free tool isn't enough, deliver from files.your-agency.com — password and view analytics included.
Eliminates manual zipping steps when sending multiple files to clients.
Lets users actually compress files right away instead of guessing output ranges.
Saves time and reduces confusion in client handoffs by standardizing delivery messages.
Helps users send oversized PDFs that fail email and portal upload limits.
Most PDF merge tools upload your sensitive documents to a server. Ours never does — everything happens in your browser with pdf-lib.
Extracting pages from a PDF usually requires uploading to a third party. This tool does it locally in your browser.
You can convert between JPG, PNG, and WEBP in one click.
No by default. Conversion keeps original dimensions unless you use a separate resize tool.
WEBP usually gives smaller file sizes at similar visual quality for modern browsers.
Yes. Use the quality slider to balance file size and visual detail.
