filehugger.comHow to compress images online
- Click Choose files (or drag & drop) and select one or more Image files. You can also paste an image from your clipboard.
- Set the quality (75% balances size and looks) and optionally cap the longest side — big camera photos shrink dramatically when downscaled.
- Press Compress images. Processing runs with a live progress indicator.
- Open the download page to save your files individually or grab everything as a single ZIP.
Why compress images?
Email limits, upload caps and slow pages all come down to oversized images. Set the quality (75% is a strong default), optionally cap the longest side for camera photos, and batch-compress the lot. If a re-encode would come out larger than your original, the tool keeps the original — you never download a worse file.
What this tool preserves — and what it changes
✓ Preserved
- Dimensions, unless you choose a max-dimension downscale
- Format by default ("Same as input"), with JPG/WebP as explicit choices
↺ Changed
- Quality is re-encoded at your slider value — the honest lever behind every "compressor"
- EXIF metadata (location, camera) is stripped by the re-encode
- HEIC/AVIF inputs come back as JPG unless you pick WebP
Known limits & edge cases
- PNG input with transparency: choose WebP to keep the alpha channel — JPG flattens it
- Downscaling is where the big savings are: the quality slider alone can’t rescue a 40 MP photo destined for a chat message
Hitting the size limit without wrecking the picture
Upload forms cap attachments at 2 MB, email chokes past 10, and a modern phone photo misses those limits by miles. This tool re-encodes images at a quality you control — 75% is the sweet spot where photos stay clean while files shrink dramatically — and can cap the longest side at the same time, which is where the biggest savings hide: a 4000-pixel camera shot downscaled to 1600 loses nothing visible on screen and drops most of its bytes.
Formats are preserved where possible (HEIC and AVIF sources come back as JPG so the results open anywhere), and each image in a batch is processed independently. The honest guidance: compress once, from the best source you have. Repeated lossy re-compression stacks artifacts — if you think you’ll need a smaller version later, come back to the original rather than compressing the compressed.

Frequently asked questions
Is this Compress Image tool free?
Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.
Can I process multiple image files at once?
Yes. Add as many files as you like — each one is processed in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
Will editing reduce image quality?
PNG output stays lossless. JPG and WebP are re-encoded once at high quality (92% by default; the compressor lets you choose), which is visually indistinguishable for photos. Each edit works from the decoded original — there is no repeated recompression.
What format will the edited image be in?
The same format you uploaded whenever possible (JPG, PNG, WebP, GIF or BMP). HEIC and AVIF inputs come back as JPG, since browsers can read those formats but not write them — the compressor additionally lets you pick JPG or WebP output explicitly.
How much smaller will my images get?
It depends on the source: photos straight from a camera or phone often shrink by 60-90% at the default quality, while already-optimized images shrink less. If a re-encode would come out larger than the original, the tool keeps your original file instead.
