AVIF-first compression, plus conversion between JPEG, PNG, WebP, and AVIF.
Up to 50 at a time, up to 30 MB each. No signup, and we keep nothing.

Auto tunes each image.
A hard cap for “under 50 KB” portals.
Empty side keeps the ratio. Never enlarges.
Four things that decide whether an image tool survives past the first upload.
The modern codec lands well under JPEG and PNG, and ~95% of browsers already read it. We reach for AVIF first, and fall back to JPEG or PNG when you need wider compatibility.
Drop a whole batch at once. Each image gets its own live meter and a before/after check. Download them one by one or as a single ZIP.
JPEG, PNG, WebP, AVIF, and iPhone HEIC go in. Keep the format, or convert to several at once in one pass.
No account, no watermark. We process uploads and wipe them automatically: we keep nothing. Privacy is the default, not a setting.
A 4964×2782 photo straight off a camera, capped to 2400px and converted to AVIF in one pass: 9.4 MB down to 67 KB, 99.3% smaller.
Three steps, no account, and a measured number at the end of each one.
Drag images in, or choose a target format first.
We sniff each file, strip metadata, and encode at the smallest size that still holds quality.
Compare before and after, grab each result, or take the whole batch as one ZIP.
A hard cap, not a hopeful slider: name the number and the file comes back at or under it, or you’re told plainly the size can’t be met. Measured output, not estimates.
Upload portals don’t negotiate: “JPG under 100 KB” means exactly that. Set Max file size in Advanced settings and the engine searches quality, and under an extreme cap, dimensions, until your file fits under the number, never over. A cap that genuinely can’t be met fails with a clear error instead of delivering mush.
Presets
Portal named the number? The size pages open with the cap pre-armed: compress to 50 KB and its 20/100/200/500 KB siblings.

How these numbers are measured: every byte count on this page is the size of the actual encoded file our engine produced from the named source image. Those are the same bytes you would download, not an estimate or a best case. Rerun any of them yourself: drop your own file into the tool above and the meter reports your real result.
Every free tier has limits. Here is what ours actually lets you do, next to the other major free compressors, with every competitor figure taken from their own pages.

|---|---|---|---|---|---|---|---|
| Exact KB target size | Yes, all four formats | No | No | No | No | Yes, JPEG only | No |

Competitor figures read from each vendor's own public pages on 7 September 2026 and verified twice against the live page, limited to what each vendor states about its free tier: "not stated" means the vendor publishes no figure, not that it has no limit. Batch size is a platform constant and applies to everyone. The other Blinkimg cells are the Free tier, which runs without an account at 30 MB a file.
If you only remember one row: AVIF for the web, JPG for compatibility, PNG when nothing may change.
| Format | Compression | Alpha | Relative size | Best for |
|---|---|---|---|---|
| JPG | Lossy | No | 100% | Photographs |
| PNG | Lossless | Yes | 190% | Graphics, screenshots, transparency |
| WebP | Lossy or lossless | Yes | 68% | Smaller web images |
| AVIF | Lossy or lossless | Yes | 42% | Smallest web images |
| HEIC | Lossy (HEVC) | Yes | 55% | iPhone photos (convert for the web) |
Not a toggle, not a promise buried in a policy. We built the system so nothing sticks around to leak.
We process your files and wipe them automatically. We never archive them, never train on anything with them, never sell or share them.
Every output ships without camera metadata or location data. Photographers can keep it with one checkbox.
No third-party trackers touch the tool, and uploads are used for your job and nothing else. The Free tier is ad-supported; paid tiers stay ad-free.
Drop files and go. Nothing ties an upload to a profile. You get 300 images a day and 100 an hour, counted live beside the drop zone.
No “contact sales” and no hidden tiers: monthly cancel-anytime, or yearly with 2 months free. Every tier includes API credits, granted once and never expiring. One balance, every surface.
2 months free
free account, no card
= $2.08/mo effective
= $7.08/mo effective
We never count a monthly total on paid tiers. Limits are per session, and Pro Max has no session limits at all.
Credits meter the API and the plugins: 1 credit per compress, 2 per convert. One balance on every surface.
Every tier ships a one-time grant, even Free (1,000). It never expires. Need more? Packs below, or pay per compression.
| Pack | Price | Per credit | Same volume on TinyPNG |
|---|---|---|---|
| 5,000 credits | $15 | $0.003 | ~$40.50 (2.7×) |
| 25,000 credits | $59 | $0.0024 | ~$115.50 (2.0×) |
| 100,000 credits | $199 | $0.002 | ~$265.50 (1.3×) |
"Same volume on TinyPNG" prices each pack's image count on TinyPNG's full published schedule (500 free, $0.009 to 10,000, $0.002 above). That is the honest blended comparison, not a flat-rate multiple. Packs never expire; pay-per-compression is also available.
The web tool and the developer API draw from the same account and the same credit balance. The WordPress and Shopify apps will too. No per-platform silos.
Paste your key once and the same engine behind this page will compress every upload, drawing on the same credit balance as the web tool and the API. One account, three places.
This site is the API’s first customer: the tool above consumes the same public endpoints. Create a key from your account. Even Free includes a one-time 1,000-credit grant that never expires. AVIF plus an exact size cap in one call:
curl -X POST https://api.blinkimg.com/v1/jobs \
-H "Authorization: Bearer bk_..." \
-d '{ "uploadId": "...",
"options": { "format": "avif",
"targetBytes": 100000 } }'Short answers. Drop one file in and the meter settles most of these in about a second.
Drop it in and the meter reports the exact saving before you download anything.
